Linear Motors

SEA MOTION linear motors are mainly divided into four series:

1.SMJ series flat magnetic linear motor with iron core

2. SMUC series intermediate magnetic linear motor with iron core

3. SMU-H series bilateral magnetic linear motor with iron core

4. SMU series bilateral magnetic linear motor without iron core

Also available is the semi-closed SMJE series.

Fully enclosed SMJD

Based on linear motors, we have also developed and produced various equipment, such as high-precision laser cutting equipment and visual recognition and inspection equipment.
