The MI-F 40 PMSM torque motor is a compact powerhouse designed for applications where precision and limited space go hand in hand.
Now available in a combined motor configuration: by stacking multiple motors, you can significantly increase torque output while maintaining a compact design.
Two MI-F 40 torque motors can be integrated into a single system, delivering up to 3.0 Nm continuous torque – without the use of gearboxes or transmissions.

About the MI-F 40
Thanks to the frameless and direct-drive design, the combined MI-F 40 solution offers high torque density with minimal moving parts. This makes it an excellent fit for compact mechatronic systems, medical robotics, food processing equipment and other lightweight applications where performance, efficiency, and reliability are critical.
Each MI-F 40 consists of:
- Stator (stationary): Generates the rotating magnetic field.
- Rotor (moving): Equipped with permanent magnets, delivering smooth and efficient rotation.
Why Combine Torque Motors?
Combining two MI-F 40 torque motors within a single cylindrical assembly enables significantly higher torque output while preserving the benefits of direct-drive technology: zero backlash, minimal maintenance, and maximum control accuracy.
Our combined motor approach eliminates the complexity and losses of traditional mechanical transmission systems, improving dynamic response while keeping your design compact and lightweight.
