Direct Drive Torque Motor

A direct drive torque motor is a permanent-magnet synchronous motor. Hence, the load is directly driven without the use of a gearbox or transmission. This reduces the number of moving parts, and thereby increases the operational lifetime and efficiency of the application.

Magnetic Innovations offers a wide range of standard torque motors for many industrial applications. We have also successfully designed and built numerous custom torque motors for different operational conditions. If you know your specific requirements and you would like to receive a quote, you can fill out our online requirements form and we will reply to you as soon as possible.

Our standard torque motors, the MI-F series, are available in three outer diameters: 110, 250 and 485 mm (~4.3, 9.8, and 191 inch, respectively). Furthermore, each series is available in standard motor heights off 25 mm, 50 mm and 75 mm (~1, 2, and 3 inch). It is also possible to customize the height of the motor, however. Combined with various winding designs and cooling options, we offer you a wide range of direct drive frameless motor designs.

The 250 mm MI-F series has a peak torque range of 121-400 Nm and a continuous torque range of 42-208 Nm. In addition, it is possible to integrate water cooling, forced air cooling and temperature control sensors for demanding applications. Examples of where these motors can be used, are in the automotive industry for vehicle propulsion and in various servo control applications.

The 485 mm MI-F series doesn’t experience limitations such as backlash, cogging and long term drift, due to a very high control loop bandwidth and direct coupling. This means that our 485 mm permanent magnet synchronous motors offer many advantages in comparison to belt or gearbox solutions. Examples of where these motors can be used, are in industrial or agricultural fan applications and for wind power generation.
