Torque motors are often used in the tape supply and take-up motors of tape drives. On such devices, the required voltage is not high, but there is a relatively stable tension on the tape. Torque motors can move forward or rewind quickly without gears and clutches. There are two kinds of DC and AC.

       The self-inductance reactance of DC torque motor is very small, so the response is very good; The output torque is proportional to the input current, independent of the speed and position of the rotor. It can be directly connected to the load at low speed in the near gridlock state without gear reduction, so it can produce a high torque-to-inertia ratio on the load shaft, and can eliminate the system error caused by the use of reduction gear.

       Ac torque motorCan be divided into synchronous and asynchronous two, the current commonly used is the squirrel cage asynchronous torque motor, it has the characteristics of low speed and large torque. Generally, in the textile workers  The AC torque motor is often used in the industry, and its working principle and structure are the same as that of the single-phase asynchronous motor, but because the resistance of the squirrel cage rotor is larger, its mechanical characteristics are softer.

       In some cases that cannot be matched with the deceleration mechanism, the torque motor can also be used as the actuator of the direct drive mechanism, such as the motion control system or the servo system.
