MI-F 250 Specifics
The MI-F-250 mm has a peak torque range of 121-400 Nm and a continuous torque range of 42-208 Nm. Furthermore, additional cooling options can be integrated for demanding applications. Our torque motors thus effectively maintain the high performance and continuous torque necessary, even for demanding applications.
Compared to brushed motors, the absence of brushes in the MI-F 250 direct drive motor eliminates mechanical wear. The load is directly driven by the motor. No gearboxes, worm gear drives or other transmissions necessary. This reduces the moving parts in the system, resulting in high operational life and reliability, while reducing the overall system cost.
Our Mid-sized PMSM torque motor offer an excellent power-to-size ratio, providing a balance between compactness and performance. The MI-F 250 series is capable of delivering substantial power output while still maintaining a reasonable physical size. This advantage makes them suitable for applications that require a moderate amount of torque and power in industries such as industrial automation, robotics, and electric vehicles.
Additional benefits are the silence and high dynamic operation the motor creates as well as its low maintenance.

Need More Torque? Combine the MI-F 250 motors
For demanding applications, the frameless MI-F 250 torque motor can be combined in stacks from two of up to five units.
Significantly boosting performance— providing a scalable solution with the same outer dimensions and direct-drive benefits (gearbox-free).
Stack up to five units to reach 520 Nm continuous and 1529 Nm peak torque, with active cooling.
Also available: Inrunner Torque Motors
We also offer Inrunner torque motors for applications where speed and precision are paramount.
Inrunner motors house the rotor inside the stator, enabling a more compact overall design. This makes them well-suited for applications with space constraints where high torque is not the primary requirement.
Our inrunner torque motor series IR-F are available in three build volumes (52 mm, 85 mm, and 170 mm), each offered in three heights (15 mm, 30 mm, and 45 mm), with torque ranging from 0.49 Nm to 70 Nm.

FAQ MI-F250
Advantages of the torque motor are: high dynamics, high torque density, high efficiency, optimal speed control, high reliability and lifetime and low maintenance.
To safeguard motor integrity for high performance applications, temperature control is required. Water cooling, forced air cooling or temperature control sensors can be integrated with the torque motors. So that applications can effectively maintain high performance.
Depending on the model the Continuous torque is between 39,9Nm and 219,8Nm. The peak torque is between 120,6Nm and 400Nm.
Direct drive torque motors contain a relatively large number of poles. This combined with different winding types results in high force and power density of the motors. As a result, the power requirements and energy consumption are generally low.
