Tips for using a torque motor with a gearbox

  • The torque motor has the characteristics of high starting torque and inclination. The speed control can be realized by changing the power supply voltage.
  • It is suitable for winding applications. In applications where an object is continuously released at a constant speed and wound at a constant tension. If the diameter of the winding spool is doubled, the torque must be doubled and the speed must be halved.
  • A torque motor with a gearbox can be used as a brake. By using the speed-torque characteristics of the motor in the braking area, it can act as a brake. In addition, constant tension operation can be realized by applying DC voltage.
