Geared Torque Motor

  • Short movement with stop position
  • SEW torque motors are AC squirrel-cage motors designed for operation with rated torque at standstill. They are comparable with springs with endless spring travel.
  • Geared torque motors move gates, flaps, or switches. They move press dies into die change position. In all cases, they serve as a drive in which a stop position must be reached and held following a short movement. Even under voltage, they can have their speed matched temporarily by another drive and then continue running at their own force.
  • Supply voltages and degrees of protection for SEW torque motors correspond to those of SEW AC motors.
  • The electrical design enables torque motors to be continuously operated in S1 duty/100% cdf with the permitted starting torque.
  • The attainable starting torque is tripled when torque motors are operated in S3 duty/15% cdf. This duty cycle is permitted only briefly (15% cdf). Continuous duty with a forced cooling fan increases the permitted S1 torque without the threefold value being reached.
  • The dimensions of DRM motors are identical with those of DR. motors of the same size. You find the dimensions of the motors in the "AC Motors" catalog, and those of the gearmotors in the "DRE Gearmotors" catalog.
  • Geared torque motors are combined from a modular system just like gearmotors. Since torque motors develop less torque in comparison to DR. motors of the same type due to thermal conditions, a greater range of possible combinations with gear units is available.
