DC torque motor, a type of torque motor powered by direct current. It is a special motor with soft mechanical characteristics and a wide speed regulation range. Unlike a motor that outputs power at a constant power, this motor outputs power at a constant torque. The DC torque motor can operate at a lower output torque but achieve a higher output speed. The speed and output torque can be independently adjusted, making it easy to use and simple to operate. It offers greater controllability compared to standard AC torque motors.




Low harmonic content in sine reverse electromotive force; typical design values for harmonic content are approximately 2.5% for the third harmonic and 0.3% for the fifth harmonic.No tooth engagement torque fluctuation.Wide torque/current linear range with high linearityHigh torque densityExtremely low hysteresis damping torqueUltra-low inductance, small electrical time constant, fast dynamic response.The installation of the stator and rotor requires low coaxiality.

DC torque motors are used in various industries such as mechanical manufacturing, textiles, papermaking, rubber, plastics, metal wire and cable manufacturing; DC torque motors can also be applied flexibly based on their multiple features: they can partially replace DC motors, be used in gate (valve) opening and closing systems with high resistance torque, and can also be employed in devices that frequently reverse direction or in various mechanical devices with similar actions.
