  • Why does stepper motor need speed reducer?
    In most cases,the planetary reducer is used with a servo motor. Mainly because the servo motor speed torque output is usually constant. The output speed and torque of the planetary reducer can be adjusted as required. And the stepper motor with planetary reducer this program, is also quietly used in the industry, the stepper motor is characterized by the speed can be set according to the required requirements, can be accurately positioned. (1)increase the motor output torque The installation size of the stepper motor is small, and it is often suitable for some systems with limited installation conditions. Due to the small size of the stepper motor, the torque is also small, and after installing the planetary reducer, it plays a role in increasing the torque when the installation flange is unchanged. (2) avoid the motor resonance area Stepper motor at low speed will appear strong vibration and noise, we call the stepper motor "resonance zone", "resonance zone" generally appears in the motor speed of (40-100 RPM) low speed range. After installing the stepper motor of the planetary reducer, the input speed of the motor is fast, and the output speed of the reducer is slow, which can successfully avoid the resonance region, making the motor run more smoothly. (3)to achieve ultra-low speed motor operation Stepper motor requires operation at ultra-low speed, many times our stepper motor is not up to, for example, 1 RPM, the installation of planetary reducer can achieve ultra-low speed operation. In the case of some ultra-low speed range stepper motors can be achieved, although the resonance area has been avoided, there will be a phenomenon of motor crawling, and the operation is not smooth. After the installation of the planetary reducer, the motor speed is increased, and the motor can run at ultra-low speed, making the motor run smoother.

  • What are the advantages of linear motor compared with ball screw?
    1.Positioning accuracy In terms of accuracy, the identification of linear motor transmission mechanism reduces the problem of interpolation lag, positioning accuracy, reproduction accuracy, absolute accuracy, and feedback control through position detection are higher than "rotating motor + ball screw", and easy to achieve. 2.Repeat precision comparison The linear motor mechanism is simple, reducing the problem of interpolation lag, on the contrary, the gap of the silver wire rod is easy to affect, so the linear motor is easier to achieve. 3.Speed comparison General servo motor due to the role of centrifugal force, high-speed operation, will be subjected to greater stress, so the speed and output power is limited. Relatively speaking, the linear motor is not limited, and the mechanical loss is also less, thus increasing the transmission speed. 4.Itinerary comparison From the stroke point of view, the stroke of the linear motor depends on the stator and the actuator, theoretically speaking, the linear motor stroke can be extended indefinitely; The servo motor + screw can only reach 4M length due to the influence of load, ball screw outside diameter, accuracy grade and other factors. 5. Easy maintenance The linear motor has few parts, no contact with the moving machinery, and little or no maintenance. The servo motor has many screw structures and many parts, which need to be maintained or replaced frequently. 6.Longevity comparison Linear motor: Because there is no direct contact between the moving parts and the fixed parts, the linear motor will not wear due to the high-speed movement of the actuator, even if the movement accuracy does not change for a long time, so the life is longer. Servo motor + screw: The ball screw causes the wear of the transmission parts due to high-speed movement, and can no longer ensure the accuracy in high-speed reciprocating motion, thus affecting the accuracy.

  • How does the stepper motor work?
    A stepper motor is a simple two-phase brushless synchronous motor consisting of a segmented magnetized rotor and a stator composed of a specified number of electromagnetic coils. When energized, these coils generate north and south poles that push or pull the segmented magnetized rotor to spin it. The diagram shows the internal structure and slot arrangement of a typical hybrid stepper motor. The fine teeth are evenly distributed around the entire diameter, causing the incremental Angle to rotate, resulting in mechanical motion. The stepper motor consists of two windings (2 phases) and is energized by direct current. When the current in one winding is reversed, the motor shaft moves one step. Reversing the current in each winding makes it easy to precisely control the position and speed of the motor, which makes stepper motors suitable for many different motion control applications. The stepping size is determined by the design characteristics of the motor, and the 1.8° stepping Angle is the most common (consisting of 200 teeth). Other stepping angles are also readily available. Divide 360° by the step Angle to calculate the number of steps required for each turn. The choice of stepper motor mainly depends on the retention torque and the corresponding rated current. Holding torque is the maximum external torque (energized at its rated current) that can be applied to a motor without causing continuous rotation. At the beginning of the motor rotation, the available torque is often referred to as the pull out torque. The pull out torque rating is expressed as a numerical value on the motor speed/torque curve. The coils of the stepper motor can be configured in a unipolar or bipolar arrangement. Simple stepper motor drive electronics can be used to sequence the coils to rotate the motor shaft, so the single-pole configuration is easiest to control. Bipolar arrangements require the use of more complex drivers to properly arrange the windings to control the motor, which also provides additional performance advantages such as higher holding torque. Stepper drivers have a wide range of rated voltages and currents. The performance of the motor is highly dependent on the current and voltage provided by the Drivers. Full step, half step, and "microstep" are common terms used to discuss stepper motors. For example, a 1.8° stepper motor has 200 discrete positions in a 360° rotation. Because 360° divided by 200 is 1.8°, every time the motor is required to move one step, the motor shaft will advance 1.8°, which is called the full step. The term "half step" refers to the 0.9° step Angle (half of the full 1.8° step Angle), which is achieved by a switching technique in which positive, no-current, and negative current are continuously and alternately applied to each winding. The term "microstep" refers to a more complex form of control that goes beyond simple power switching between the motor phase windings to control the current flow sent to the individual windings. One of the main benefits of microstepping is the ability to reduce the resonance amplitude generated by the motor when operating at natural frequencies. Microstepper allows the shaft to be positioned beyond the 1.8° or 0.9° provided by full and half steppers. The microstep position appears between the two corners of the rotor rotation. The most common microstep increments are 1/5, 1/10, 1/16, 1/32, 1/125, and 1/250 of the full step.

  • Linear motors VS rotary motors: what's the difference?
    Linear motors, as the name suggests, produce linear motion. They consist of a stationary part, called the stator, and a moving part, called the rotor. The stator contains a series of magnets, while the rotor contains a coil of wire. When an electric current is passed through the coil, it creates a magnetic field that interacts with the magnets in the stator, causing the rotor to move in a linear direction. Linear motors are commonly used in applications where straight-line motion is required, such as in conveyor systems, high-speed trains, and CNC machines. On the other hand, rotary motors produce rotational motion. They consist of a rotor and a stator, similar to linear motors. The rotor contains a coil of wire, while the stator contains a series of magnets. When an electric current is passed through the coil, it creates a magnetic field that interacts with the magnets in the stator, causing the rotor to rotate. Rotary motors are widely used in various applications, including electric vehicles, industrial machinery, and household appliances. In terms of advantages, linear motors offer high acceleration and deceleration rates, precise positioning, and the ability to achieve high speeds. They also have a simple design and do not require additional mechanical components, such as gears or belts. However, linear motors can be more expensive than rotary motors and may require more complex control systems. On the other hand, rotary motors are more commonly used and widely available. They are generally more cost-effective and have a higher power-to-weight ratio compared to linear motors. Rotary motors also have a well-established design and are easier to integrate into existing systems. However, they may not be as suitable for applications requiring straight-line motion or high speeds. In summary, linear motors are used for linear motion applications, while rotary motors are used for rotational motion applications. The choice between the two depends on the specific requirements of the application, including the type of motion needed, speed requirements, and cost considerations.

  • Linear motor vs. linear actuator: What's the difference?
    A linear motor and a linear actuator are both devices used to generate linear motion, but they operate on different principles and have different applications. A linear motor is a type of electric motor that produces motion in a straight line rather than in a rotational manner like traditional motors. It consists of a stator (stationary part) and a mover (moving part). The stator contains a series of magnets, while the mover consists of a coil or a set of coils. When an electric current is applied to the coils, a magnetic field is generated, causing the mover to move along the length of the stator. Linear motors are typically used in high-speed applications where precise and rapid linear motion is required, such as in industrial automation, transportation systems, and robotics. On the other hand, a linear actuator is a mechanical device that converts rotational motion into linear motion. It consists of a motor (usually a rotary motor), a screw, and a nut. The motor rotates the screw, and as the screw turns, it moves the nut along its length, resulting in linear motion. Linear actuators are commonly used in applications where controlled linear movement is needed, such as in home automation, medical equipment, and automotive systems. In summary, the main difference between a linear motor and a linear actuator is the principle of operation. A linear motor generates linear motion directly through the interaction of magnetic fields, while a linear actuator converts rotational motion into linear motion using a screw mechanism.

  • What are the working principles and characteristics of linear motor?
    The linear motor is a transmission device that converts electrical energy directly into linear motion mechanical energy without any intermediate conversion mechanism.It can be regarded as a rotating motor that is cut radially and spread out into a plane.The side evolved from the stator is called the primary,and the side evolved from the rotor is called the secondary.For practical applications,the primary and secondary are manufactured in different lengths to ensure that the coupling between the primary and secondary remains unchanged over the desired travel range. Linear motors work in a similar way to rotary motors.Take linear induction motor as an example: when the primary winding is connected to the AC power supply, the traveling wave magnetic field is generated in the air gap,and the secondary traveling wave magnetic field is cut,the electromotive force is induced and a current is generated,and the current interacts with the magnetic field in the air gap to produce electromagnetic thrust.If the primary is fixed,the secondary moves in a straight line under the action of thrust;On the contrary, the primary motion is linear.A linear motor application system must not only have a linear motor with good performance,but also must have a control system that can achieve technical and economic requirements under safe and reliable conditions. Because the linear motor can produce linear motion without any intermediate conversion mechanism,it is especially suitable for linear motion occasions.Compared with traditional rotary motors,devices driven by linear motors have the following advantages: (1) The linear motor mover can be directly connected with the load to produce linear motion,without the need for intermediate transmission mechanisms such as chains and lead screws, which can greatly improve the transmission efficiency. (2) Due to the lack of intermediate transmission connection accessories, the linear motor motion system has a simple structure,which reduces the noise interference caused by mechanical friction,and because of its simple structure, it can improve the reliability of the system. (3) The linear motor can produce a very high linear speed through its own extreme acceleration in a short stroke. (4) The linear motor is not bound by centrifugal force, so its linear running speed is also unlimited. (5) The primary shape of the linear motor is regular, easy to package, and the armature winding after it is placed can be packaged with chemical materials such as epoxy resin, so that it is free from the intrusion of chemical liquids or rain, and can be more convenient for application in harsh working environments.

  • Why use linear guides and ball screws with ball chains?
    One difference between radial ball bearings and recirculating ball linear guides is that radial bearings usually use cages to separate the balls and control their movement,whereas profiled guides do not.But in the early 2000s,manufacturers of profiled rail bearings began to introduce versions with ball cages(also known as "ball chains" or "ball separators")to improve bearing life,operating characteristics and noise.The incorporation of ball separators into ball screw nuts came a few years later,as manufacturers had to address unique design and material challenges caused by the more complex recirculation path the ball chains had to travel. Some manufacturers now offer all or most of the profiled guide bearings and ball screw nuts with ball chains.For many applications - especially those that can benefit from low noise,smooth operation and infrequent lubrication-linear guides and ball screws with ball separators make sense.In many cases,manufacturers that provide pre-assembled and integrated systems,such as linear actuators or pre-assembled screw drivers,default to the ball chain form of linear guides and ball screws. Ball chains can be incorporated into ball screw nuts and profiled linear guides to improve operating performance and reduce noise. In any bearing,when the ball is rolling freely(or sliding)without the guide of a cage or chain,the ball will come into contact with each other due to the different speeds at which they enter and leave the load zone.This contact creates friction and audible noise.The ball chains prevent the balls from touching each other,thus reducing friction and,therefore,heat,which extends the service life of the bearing or nut.The noise is reduced because the ball is no longer metal-to-metal but metal-to-polymer(or metal-to-resin)contact. The basic purpose of the ball chains is to separate the balls from each other - to prevent them from touching when the bearing seat moves on the guide rail or the ball nut rotates on the screw shaft. The reduction of heat actually provides a double benefit,as the less heat,lubrication the lubricating oil can also be held and delivered in a more efficient manner due to the"pockets"that the ball chain forms around the ball.These pits trap lubricating oil and ensure better delivery of grease or oil to each ball.Some manufacturers use ball chains in their"high speed"series of profiled guide bearings and ball screws,but the ball chains must be strong enough to withstand the forces generated by sliding and bending at these high speeds. Providing consistent fixed spacing between balls also improves operating characteristics by reducing the variation in friction that occurs when the balls are unevenly spaced.The distance between the ball bearings is consistent,the movement is more controllable,the rolling resistance changes less,and the running stability is better.For applications that require extremely smooth running characteristics,the use of profiled linear guides or ball screws with ball chains is a good way to meet the application requirements without the need for more expensive technology,such as air bearings or linear motors. Do not confuse ball chains(aka ball cages)with spacer balls.The spacerball is slightly smaller than the bearing ball and is used to reduce friction and noise during ball contact.But when spacer balls are added to linear bearings or ball screws,some of the bearing balls have to be removed,which means that the carrying capacity and stiffness is reduced. https://www.seidal-tec.com/linear-guideways/

  • Which linear guides are interchangeable?
    Linear guides in an existing machine or component need to be replaced for a variety of reasons:by replacing bearings with higher preloads to improve the stiffness of the component,or by using a different bearing type or style to accommodate unforeseen space constraints.Sometimes,linear guides need to be replaced just for maintenance and repair. Whatever the reason for the swap,the process of replacing linear bearings is not always as simple as ordering new components and installing them on the machine.For some products,components from different manufacturers are not interchangeable,regardless of style or size.Even within a given manufacturer's product line,not all components are interchangeable.Before you attempt to replace linear bearings,shafts,or guides,here is a guide to which types are(and cannot be)interchangeable and what determines their interchangeability. In this case,"style" means the general shape of the housing - its length(standard,short or long),width (standard or wide),and whether it has a flange."Style" can also refer to how many rows of ball bearings the bearing has - two,four or six rows. Round shaft linear bearings Round shaft versions are the easiest to replace and "mix and match" straight bearings because most are interchangeable in size regardless of manufacturer or style.However,due to different ball recirculation methods,load capacity can vary greatly between manufacturers and styles,which can affect the load capacity of bearings.In addition to the options and flexibility offered by circular shaft bearings,many types and sizes of plain bearings are interchangeable with common cycle styles. Round shaft guides Interchanging Round shaft guide is a simple process due to their simple geometry and small range of materials and hardness grades.Their main specifications are diameter,diameter tolerance and shaft hardness.As long as these three parameters match or are suitable for application, any shaft from any manufacturer can be used with any sliding or circulating bearing of the same size. Round shaft linear bearings and guides are relatively easy to interchange due to their simple geometry. Profiled rail bearing blocks Due to the difference in geometry and size of bearings and guide raceways,it is not possible to use a Profiled rail bearing from one manufacturer with a guide from another.Therefore,if only one component(bearing or rail)needs to be replaced,it must be from the same manufacturer as the original. On the other hand,if two components need to be replaced,in some cases the entire component can be swapped from one manufacturer to another.This is because the sizes and styles of some of the most commonly used profiled rail assemblies have the same external dimensions(height,width,mounting bolt pattern)between manufacturers. Manufacturers sometimes use the term "random matching" to indicate that the products in their profiled guide products are interchangeable.When manufacturers change their product lines from one type of irregular track bearing to a different style or preload,keep in mind that interchangeability is not always provided in the design. This is because in order to "mix and match" different bearing seats and guides of a given size,the raceway position on the guide and bearing seats must be very precisely controlled.Normally,preloaded bearing blocks are not interchangeable because the tolerance between guide and bearing affects the amount of preload. Whether bearing blocks of different styles(flanged,short,long,etc.)and preloads will fit on a guide rail depends on both the manufacturer and the design. Profiled rail guides As with the profiled rail bearing blocks,the Profiled rail guide is not interchangeable between manufacturers.However,in the manufacturer's product line,Profiled rail guides are usually interchangeable,as long as they have the same style,meaning that the number of raceways and the design are the same.

  • Can linear actuator provide the rigidity and accuracy of linear stage?
    Although there is no industry standard that defines linear actuators and linear loading platforms,generally accepted terminology indicates that linear actuators are typically constructed of aluminum extruded parts or bases,while linear loading platforms are typically built on flat,machined steel or granite bases. This difference means that linear actuators can provide longer strokes and use a variety of drive mechanisms(belts,screws,rack and pinion),while platforms typically have higher rigidity and use high-precision linear guides and drive mechanisms(usually ball screws or linear motors)for excellent travel and positioning accuracy. But one actuator design - the U-shaped linear actuator - ignores these specifications and uses an extruded steel base to provide rigidity and stroke accuracy specifications comparable to some linear stages. Seidal KK Linear Module The use of steel(rather than aluminum)profiles makes the U-shaped design very robust and allows manufacturers to offer linear actuators with high stroke and positioning accuracy,typically found in more accurate,more expensive linear platforms.The steel base may also be machined to provide a reference edge for accurate alignment with other machine parts or other actuators in a multi-axis system.U-shaped linear actuators have very high rigidity and are better suited than other designs for applications where only one end of the actuator is supported,such as 2-axis and 3-axis Cartesian systems. Seidal Linear Actuator The U-shaped linear actuator consists of an extruded steel base.The linear guide raceways are ground into the base,and the slide or slide block resembles a bearing block that turns from the inside out,allowing the ball nut to fit in the center.This design makes the whole package very compact and strong. Despite its compact size,the U-shaped linear actuator has excellent load and torque capabilities.This is because the raceways are relatively far apart,so the geometry of the slider is similar to the geometry of the bearing seat and is much larger than the actuator can accommodate in its standard form. Originally developed for high-precision applications such as semiconductor wafer processing and medical diagnostic dispensing,where space constraints did not allow the use of typical linear platforms,U-shaped linear actuators are now used in a variety of industries and applications. These include plasma welding,automatic assembly and optical inspection. https://www.seidal-tec.com/kk-linear-module/

  • What are the main types of linear actuators?
    Belt and screw driven actuator Although belt drive and screw drive are different technologies,it makes sense to put them in the same category because they are the two most common electromechanical actuators.Most linear actuator manufacturers offer belt drive and screw drive options. Belt drive actuators can use a variety of guiding mechanisms,the most common of which are plain bearings,cam-roller rails, and circular bearings(mounted on a shaped rail or circular shaft). Because of their advantages of high speed and long travel,belt drives are usually installed in aluminum extrusions or open construction with no protective housing. Ball screw driven actuator Within the category of screw drives,there are two subcategories-ball screw drives and lead screw drives.Although ball screw actuators have higher repeatability and thrust than screw actuators,both provide inherent transmission through the lead of the screw(pitch). The most common guide system for screw drive actuators is a special-shaped guide rail,although sometimes the lead screw type is guided by a plain bearing.Because screw drive actuators require end bearings and must be rigidly mounted,they are usually packaged in aluminum extrusions.However,when high stroke accuracy is required,ball screw types are usually provided with machined steel housings. Pneumatically driven actuators Although they are not electromechanical devices like other types of actuators,their popularity in automation devices makes pneumatically driven actuators an important category of linear actuators.Pneumatic actuators can be further divided into two subclasses:slider type and rod type. In a slider type actuator,the motion is contained within the limits of the housing,and the load is mounted to the slider(also known as the slide frame,saddle,or bench).In a rod actuator,the motion is generated by a rod extending and retracting from the housing.The load can be mounted at the end of the rod,or the rod can be used to push the load.(Think pressing or embossing a label on a carton,or pushing a defective product along a conveyor belt into a diverter channel.) The slider type pneumatic actuator may be guided by either a circulating bearing or a sliding bearing,depending on its design load.Rod versions are generally not designed for radial (down/up/side)loads and use simple plain bearings to provide guidance for the rod without significantly increasing the carrying capacity. The rack and pinion driven actuator For extremely long lengths and robustness to contamination,rack and pinion drives are usually the best choice.However,these characteristics make it difficult to find suitable guidance systems in some applications.For extremely long lengths,connected special-shaped rails are sometimes used,but when contamination is a significant problem,metal wheels are usually preferred. A unique feature of rack and pinion types is their ability to independently drive multiple brackets.A common application of rack and pinion actuators is elevated gantry,usually found in automotive production. Linear motor driven actuator Linear motor actuators can also achieve long travel in the case of multiple brackets,but they are mainly used for high precision,high dynamic motion.To complement the advantages of linear motors,these actuators use high-precision special-shaped guides,cross-roller guides,and even air bearings as their guide systems. Linear motor types can be mounted on extruded housing or machined aluminum sheets,but to meet the highest stroke accuracy specifications,they can also be mounted on machined steel sheets or granite bases.Compared to high cost magnetic track linear motor on market,seidal MTF Linear Motors can save on large amounts of rare-earth materials bring at least 70% COST SAVING, particularly on long track linear motors. https://www.seidal-tec.com/kk-linear-module/ https://www.seidal-tec.com/mtf-linear-motors/
