Your advantages

Full torque
is delivered by the rotary field magnet even when the rotor is blocked.

No damage in the event of blockage
and no damage in the opposite direction of rotation, as the motor is designed for this.

Flexible use
thanks to rotary field magnets in 3 different rated torques. This means we can supply you with the optimum drive for your application.

DRM../DR2M.. torque motors: short movement - secure hold

The torque motor DRM../DR2M.. is a low-speed motoring operation designed for operation with rated torque at idle state. It is the optimum drive for all applications in which a stop position must be reached and held safely after a short movement. This type of motoring operation is usually referred to as a "rotary field magnet" for short.

With us, you will find the right motor for a wide range of requirements and speeds - together with a gear unit. This is because we offer every rotary field magnet in three rated torques. In addition, the rotating field magnet DRM../DR2M.. rotary field magnet is permanently thermally protected even when the rotor is blocked.

Our rotating field solenoids require a 3-phase three-phase supply. The electrical design allows the rotary field solenoids to be operated in operating mode S1 with 100% cyclic duration factor when the rotor is blocked. This means that the rotary field solenoid continuously delivers the full, approved torque.

However, if your application only requires a particularly high torque for a short time, we recommend operating mode S3. In this operating mode, the motor runs with a 15% cyclic duration factor and achieves up to three/five times the rated torque. Ideal for press tools, for example.

Of course, the rotary field magnets and you can use many additional features of the AC motor from the DR... series.

  • Motors of the DRM../DR2M.. series can also be operated temporarily under stress by another drive and then continue to run under their own force
  • The connection voltages and degrees of protection of our rotating field magnets correspond to our DR... AC motors.
  • Three operating modes are available:
    • Operating mode S1, 0.7 Nm to 3.6 Nm
    • Operating mode S3/15%, 2.6 Nm to 17.3 Nm
    • Operating mode S1 with forced cooling fan, 1.9 Nm to 8.7 Nm
