38 Series

Frameless Torque Motor

1.Modular stator and rotor design with optimized magnetic circuit improves the motor’s torque density.

2.The rotor features a large internal hollow space, and the stator can be installed using the customer’s embedded mounting method, allowing flexible customized designs, including installation configurations, and providing greater adaptability for customer-specific systems.

3.Optimized slot-pole combination reduces cogging torque, ensuring smoother motor operation.

4.Compact structure with high integration capability.
