• Linear Motors

    Linear Motors JTK Series

    The air-core type linear motor is suitable for precision motion because there is no cogging thrust.
    The maximum thrust range is 30N ~ 3000N, and the motor efficiency is relatively lower than the iron core type.
    The maximum thrust range is 30N ~ 3000N, and the motor efficiency is relatively lower than the iron core type.

  • Rotary DD Motors

    Rotary DD Motors JTR24 series

    The JTR24 series is a direct drive rotary motor.
    Outer diameter is 240mm, hollow is 52mm, interior is typical.
    High precision can be realized by adopting optical encoder.

  • Motion Stages

    Frame base Gantry Stage

    There are gantry, hybrid, cross type.
    Improvement in reducing cost, weight and delivery time is achieved by the development of stages without granite base.
    It is suitable for repair device or inspection machine which requires high speed operation.
