S250D Linear Motor

Linear shaft motor design advantages:

Power dense, compact, and efficient design easily integrates into machine structures.
Zero cogging for ultrasmooth motion required for high precision applications.
Contactless motion for maintenance free operations, minimizing downtime.
Non-critical air gap with no variation in force along the length of the shaft delivers smooth and quiet operation.
Ideal for replacing ball screw actuators, flat or u-channel linear motors, or pneumatic/hydraulic systems.
