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

コア付リニアモータ

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

コアレスリニアモータ

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

円弧リニアモータ

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

真空リニアモータ

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

Q2What precautions should I take when using a linear motor for the first time?

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.

We will be happy to provide advice if needed.
Please feel free to contact us.

Q3What if we want you to check if the motor we selected is correct?

If you send us the following documents, our engineers will check them for you.

  • Selection results
  • Conditions related to kinematic performance (weight of movable objects, maximum speed, acceleration, stroking, etc.)
  • Operation pattern (for one cycle)
  • Schematic diagram of the device, if available

Contact Us

Q4What kind of amplifier should I use?

It is necessary to use different amplifiers depending on the performance of the equipment to be produced.

  • Sodick's amplifiers are available in "PMW amplifier", "High frequency amplifier" and "Linear amplifier".
    • PWM amplifier" and "High frequency amplifier" are recommended for high-precision positioning by direct command from a high-level controller.
      If you want to avoid noise from the amplifier, "Linear amplifier" is recommended.
  • For general-purpose amplifiers, we recommend "*Panasonic amplifiers".
    • If you want to control by puzzle row, etc., "Panasonic amplifier" is recommended.

      "Panasonic amplifier" = "AC servo amplifier for linear motor drive" manufactured by Panasonic Corporation.

    Note!When using Sodick amplifiers, please note that there are restrictions on the upper controller.
