A Complete Guide to Zhiying’s Linear Motor Solutions

In the evolving world of precision motion control, linear motors have become a cornerstone for industries seeking speed, accuracy, and reliability. Linear motors provide direct linear motion without the use of mechanical transmission elements, offering a superior alternative to traditional systems reliant on belts, gears, or screws. Among the players in this specialized field, Zhiying Motor (Smartwin) stands out as a premier supplier of high-performance linear motor solutions.

With a robust foundation in innovation, engineering excellence, and a customer-centric approach, Zhiying has developed a diverse portfolio that addresses the nuanced requirements of modern automation, semiconductor, life sciences, and precision machinery industries. This guide offers a comprehensive look at Zhiying's linear motor offerings, their advantages, application areas, and how to select the ideal motor for your needs.

What Is a Linear Motor?

A linear motor is an electric actuator that generates straight-line motion directly from electromagnetic forces. In essence, it is a rotary motor that has been “unrolled” to produce linear instead of rotary output. The motor consists of two main parts:

• Forcer (primary): Contains coils that generate a magnetic field.

• Platen (secondary): Usually fitted with magnets or a magnet track.

When current is applied to the coils in the forcer, a magnetic field interacts with the magnets in the platen, creating motion. This motion is linear and direct, bypassing the need for intermediary components like screws or belts, resulting in zero mechanical backlash, improved responsiveness, and higher reliability.

How Linear Motors Work

The principle of operation is based on Lorentz force law, which describes the force on a charged particle in an electric and magnetic field. In linear motors:

1. Electric current flows through the forcer (typically in a three-phase configuration).

2. The current produces an alternating magnetic field.

3. This field interacts with the permanent magnets in the platen.

4. A direct, linear force is generated along the axis of motion.

This method allows for a very smooth, precise, and fast actuation with minimal mechanical wear.

Types of Linear Motors Offered by Zhiying

Zhiying offers a complete lineup of linear motors to meet diverse industrial requirements. Here are the key types:

1. Iron-Core Linear Motors (e.g., CUM Series)

Applications: CNC machinery, packaging systems, general automation

Iron-core linear motors from Zhiying are built for high thrust and robust thermal performance. Their laminated iron core enhances the force-to-size ratio, making them ideal for heavy-duty applications that demand high continuous and peak forces.

Features:

• High force density

• Efficient heat dissipation

• Cost-effective in terms of force per dollar

• Suitable for high acceleration and deceleration cycles

Technical Highlights:

• Continuous force: 65 N to 1200 N

• Peak force: Up to 2750 N

• Optional water-cooling system for thermal-intensive applications

Limitations:

• Presence of cogging force due to the iron core, which may cause slight velocity ripple

2. Ironless (Coreless) Linear Motors

Applications: Semiconductor, medical devices, optics, precision metrology

Zhiying's ironless linear motors offer ultra-smooth motion with zero cogging, thanks to the absence of iron in the forcer. This design eliminates magnetic attraction to the platen, resulting in virtually frictionless travel and better dynamic response.

Features:

• No cogging or hysteresis

• Lightweight, ideal for high-speed applications

• Compact and efficient design

Technical Highlights:

• Positioning accuracy: Within ±1 µm

• Peak force: 50 N to 600 N

• Excellent for cleanroom or lab environments due to low particle generation

Limitations:

• Lower thrust output compared to iron-core motors

• Higher cost per unit force

  
  
  

3. Linear Servo Motor Modules

Applications: Pick-and-place machines, printing, high-speed inspection systems

Zhiying also provides pre-assembled linear motor modules that include:

• Linear motor (iron-core or ironless)

• Integrated encoder

• Optional guide rails or bearings

• Aluminum baseplate for mounting

Benefits:

• Turnkey plug-and-play motion systems

• Simplified integration

• Shorter development cycles for OEMs

These modules are ideal for developers who want high-performance motion without dealing with integration challenges.

Advantages of Zhiying Linear Motors

Zhiying's linear motor solutions offer significant benefits across a variety of operating conditions and industries:

High Speed and Acceleration

Linear motors can achieve extremely high speeds (up to several meters per second) and accelerations (over 10G) due to the direct drive nature and low moving mass.

Precision and Repeatability

These motors provide sub-micron level positioning accuracy and excellent repeatability, making them ideal for advanced manufacturing processes.

Long Lifespan and Low Maintenance

With no mechanical contact, there is minimal wear, ensuring extended life and reduced maintenance needs.

Compact and Scalable Design

Linear motors are compact and scalable, fitting into tight spaces or modular setups, perfect for flexible and compact machine architectures.

No Backlash or Compliance Issues

The absence of mechanical transmission elements means no backlash, increasing motion fidelity and control.

Key Considerations When Choosing a Linear Motor

When selecting a linear motor, consider the following factors to ensure optimal performance and cost-efficiency:

1. Stroke Length

Defines how far the motor needs to move. Linear motors can handle from a few millimeters to several meters depending on design.

2. Load Requirements

Determine the moving mass or external force that needs to be countered.

3. Speed and Acceleration

Application speed dictates the need for either high-force iron-core or fast-response ironless motors.

4. Precision

Higher accuracy applications may require ironless motors and higher-resolution encoders.

5. Cooling

Consider air or water cooling based on the duty cycle and thermal load.

6. Environmental Conditions

Temperature, humidity, and cleanliness all affect motor choice. Ironless motors are preferred in cleanrooms.

7. Budget

While ironless motors offer better precision, they are more expensive. Match motor performance to cost constraints.
