MI-F 110 Specifics
The MI-F 110 high torque motor is a part of our MI-F series. The motors in our MI-F torque motor series are outrunner permanent magnet synchronous motors (PMSM). This means the rotor of permanent magnets revolves around the stator with coils. As a result, the generated force acts on a maximum radius within the available motor volume, creating high torque. It also often eliminates the necessity for a transmission.
With the use of our magnetic and thermal simulation software, our frameless high torque outrunner motors are designed to produce unmatched performance.
Magnetic Innovations is specialized in the outrunner typology. Compared to inrunners, outrunner direct drive torque motors are capable of producing more torque and are more efficient. Moreover, the MI-F series are characterized by extremely low cogging and good thermal performance.
To maximize the torque of our direct drive motors, we use innovative winding configurations combined with optimized permanent magnet technology. A 3-phase sinusoidal current amplifier can be used in combination with the torque motor, which guarantees smooth rotation with low torque ripple.

Also available: Outrunner Torque Motors
For applications requiring higher torque at lower rotational speeds, we also offer Outrunner Torque Motors. These motors deliver exceptional performance by positioning the rotor outside the stator. This design allows for increased torque density, making outrunners ideal for applications demanding significant torque in compact spaces.
Outrunner motors are particularly suited for industries where low-speed operation with high torque is critical. Both inrunner and outrunner motors share similar advanced features, but outrunners excel in scenarios where torque output takes precedence over high-speed performance.
FAQ MI-F 110
Advantages of the torque motor are: high dynamics, high torque density, high efficiency, optimal speed control, high reliability and lifetime and low maintenance.
There are two types of direct drive frameless torque motors: the outrunner and the inrunner torque motors. In case of the outrunner motor, the rotor is located on the outside of the stator. Outrunner motors produce more torque for the same build volume compared to inrunner motors.
Depending on the model the Continuous torque is between 5,4 Nm and 23 Nm. The peak torque is between 19 Nm and 57 Nm.
A direct drive torque motor can help achieve good thermal performance through its design and construction. The absence of mechanical components like gears or belts reduces friction and power losses, minimizing heat generation. Additionally, the motor’s larger surface area allows for efficient heat dissipation, maintaining lower operating temperatures and ensuring reliable performance.
