far exceeding traditional ball screws (1.5g/120m/min).

Precision Positioning

With no mechanical backlash, positioning accuracy reaches 0.1µm and high repeatability, making it suita

ble for high-precision applications such as semiconductor processing.

Simplified Structure and Long Life

The elimination of intermediate transmission components reduces maintenance requirements, minimiz

es mechanical wear, and significantly extends life.

Fast Response and Wide Speed Range

With a speed ratio of up to 1:10,000, it can reach maximum speed instantly and stop quickly even at 

high speeds.

Modular Design

Supports multi-axis configurations, facilitating integration into automation equipment such as high-

speed conveyors and other industrial applications.

The core advantages of high-acceleration moving-stator linear motor actuators with guide rails lie in 

the high dynamic response, high precision, and low maintenance offered by direct drive, making them 

particularly suitable for applications requiring rapid start-stop and precise positioning.

I. High Dynamic Performance

High acceleration: The moving part has low mass, and the electromagnetic force acts directly, resulting 

in acceleration reaching tens of times the acceleration due to gravity (g), far exceeding traditional rotary 

motor + ball screw systems.

High speed: The maximum speed is limited only by the control system and bearings, reaching several 

meters per second or even higher.

Fast response: With virtually zero transmission stiffness and zero backlash, it responds very quickly to 

control signals, resulting in minimal tracking error.

II. High Precision and High Resolution

Direct drive:  Without intermediate mechanical transmission links, it eliminates backlash, elastic deforma

tion, and friction, achieving positioning accuracy of micrometers or even nanometers.

High rigidity: There are no elastic elements between the drive unit and the load, resulting in high motion

 rigidity, good overall system rigidity, and strong resistance to disturbances.

III. Low Maintenance and Long Lifespan

Maintenance-free: There is no mechanical contact between the primary and secondary parts, avoiding 

mechanical wear and significantly reducing maintenance requirements and maintenance costs over the 

lifespan.

Long lifespan: Non-contact drive, minimal friction and wear, high reliability, and long lifespan.

IV. Flexibility and Cleanliness

Flexible stroke length: By increasing the stator length, theoretically any stroke length can be achieved, 

and the performance does not easily degrade over long strokes.

Quiet and clean operation: No mechanical friction or impact, resulting in low noise; no lubrication is 

required, eliminating the possibility of oil contamination, making it suitable for cleanroom environments.

V. Application Scenarios

Semiconductor field: High-precision linear motion, such as photolithography machines and wafer 

handling.

CNC machining centers: High dynamic response, such as high-speed milling and laser cutting.

Automation equipment: High-precision positioning, such as robots and assembly lines.

Magnetic levitation trains: High-speed, low-noise operation.

Medical equipment: Clean, low-noise environment, such as surgical robots and imaging equipment. 

VI. Conclusion

High-acceleration moving-stator linear motor actuators with guide rails have broad application prospects

 in fields such as semiconductors, CNC machining, automation equipment, magnetic levitation trains, 

and medical devices, thanks to their high dynamic performance, high precision, low maintenance, and 

flexibility.

The High Acceleration Moving Stator Rail Linear Motor Actuator is a direct-drive transmission device 

designed for extreme dynamic response. Its core feature lies in its revolutionary approach to the traditional 

"moving stator, stationary stator" model, employing a stator coil assembly as the moving part while the 

magnetic track remains stationary. This design significantly reduces motion mass because the coil windings

 are typically lighter than rare-earth magnetic tracks, resulting in higher acceleration and faster acceleration/

deceleration performance with the same thrust. It is particularly suitable for applications with extremely

 high cycle time requirements, such as semiconductor die bonders, laser cutting, and high-speed precision 

dispensing.

This actuator is directly driven by electromagnetic force, eliminating the need for intermediate conversion

 mechanisms such as gears and belts. This eliminates mechanical backlash and friction, resulting in quiet 

operation and achieving micron-level or even nanometer-level positioning accuracy. Its structure often 

employs a coreless design to completely eliminate cogging effects, ensuring smooth operation at low 

speeds. Combined with high-resolution linear encoder feedback, it provides superior trajectory tracking 

capabilities, making it a key component for improving production efficiency in high-end intelligent manufa

cturing equipment.

The FSKH 120 linear motor employs a contactless drive mechanism, achieving micron-level positioning accuracy, rapid response speeds, and powerful thrust. Suited for long-stroke applications, it combines high-speed operation with long-term stability, making it ideal for fields such as precision machining.

Linear motors and linear modules are two distinct types of motion transmission components. Their core differences lie in their operating principles, performance characteristics, and application scenarios. Furthermore, they share a unique relationship: when linear modules are categorized by their drive type, the category itself includes modules driven by linear motors (known as "linear motor modules"). The specific core distinctions are detailed below:

1. Operating Principle

Linear Motor: Directly converts electrical energy into mechanical energy for linear motion. It requires no intermediate conversion mechanisms and drives the load directly through electromagnetic force.

Linear Module: An integrated motion unit that relies on intermediate mechanisms—such as ball screws or synchronous belts—to convert rotational motion into linear motion. Only "linear motor modules" utilize a linear motor as their driving source.

Table

Performance | Linear Motor | Linear Module (Ball Screw/Synchronous Belt Type)

Accuracy | Higher; achievable accuracy of 0.001 mm | Typically falls within the 0.005–0.04 mm range

Speed & Acceleration | Max speed up to 300 m/min; acceleration up to 10g; faster response times | Ball screw types typically reach speeds of 120 m/min with acceleration of approximately 1.5g

Noise | No mechanical contact friction; lower noise levels | Contact friction between transmission components results in higher noise levels

Stroke | Theoretically unlimited | Limited by the length of the ball screw or structural profile; fixed stroke length

Price | Superior performance; typically several times more expensive | Lower cost; offers higher cost-effectiveness

3. Selection and Application Distinctions

Choose linear motors when pursuing ultimate precision and speed, or when long travel distances are required; they are predominantly used in high-end applications such as laser cutting, precision inspection, and aerospace. Choose standard linear modules when prioritizing cost-effectiveness and meeting medium-to-heavy load requirements; they remain the mainstream choice for the majority of automated production lines and general-purpose processing equipment.
