Customers who are considering a linear motor
for the first time
Advantages of Linear Motors
Linear motors are said to have superior travel speed and positioning accuracy compared to motors with ball screw construction.
They also have high responsiveness and long-term stability due to less mechanical contact. Sodick's linear motors have a unique cooling structure, and we have accumulated a wealth of technology related to linear motors, including the know-how to design and produce the optimum linear motors for various types of machinery and equipment.
Types of Linear Motors
1Linear motor with core
The structure of a coil wound around a core (iron core) can generate a large thrust force. On the other hand, the generation of attraction (cogging) between the magnet plates results in inferior speed stability compared to coreless motors.
Main applications of core-equipped linear motors
- Electrical discharge machines, machining centers
Precision machine tools and various production machines that require large thrust force.
2Coreless Linear Motor
It is characterized by smaller speed fluctuations compared to cored components. As a machine component, it increases rigidity and, in combination with a high-performance servo system, provides excellent control performance.
Main applications of coreless linear motors
- FPD manufacturing equipment, semiconductor manufacturing equipment
- High-precision laser processing machines
Used in precision machine tools and manufacturing equipment requiring high precision.
3Arc Linear Motor
Arc-type coreless linear motors capable of rotary motion and micro-angle control.
Main applications of arc linear motors
- Rotary motion and micro-angle control are required.
Industrial machinery, machine tools
4Vacuum Linear Motor
Linear motors are equipped with a cooling mechanism to suppress outgas emissions, which can be a problem in vacuum environments. Coreless and cored types are available.
Applications of Vacuum Linear Motors
- FPD manufacturing and transport equipment, semiconductor manufacturing equipment, etc. used in a vacuum environment

-
If you use a linear motor,
you will need a linear scale to check the position of the motor.
Since linear motors are vulnerable to disturbances, the placement of the motor and the rigidity of the equipment are important, and the location of the linear scale is also important.
