The DRM.. motor in the modular DR.. series motor system is a 12-pole motor that allows for thermally safe operation on a 3-phase mains supply, even if the rotor is blocked. The usual product designation “torque motor” is also maintained for the DRM.. motor.
Every torque motor is available with 2 rated torques. Rating 2 can be three times the torque of rating 1 but either only in S3/15% cdf or in S1 continuous duty with forced cooling fan only.
