70Since the ages,Ac torque motorIt has been used in winding devices such as film development, light industrial chemical fiber, textile, cable, plastic and paper making. Speed control is achieved by the speed feedback of the speed measuring motor and the control of the tension size of these two methods todayMori machineXiaobian will take you to understand its classification:

       Torque motors are also commonly calledTorque motorIt is a flat type multi-pole permanent magnet DC motor; For high output torque and low speed. There are two kinds of distinctions, DC and AC. The former uses a flat structure with large internal holes, which is conducive to the motor being directly installed on the load shaft, improving the coupling stiffness of the system, making the system respond quickly, broaden the frequency band, work stably, and meet the dynamic performance requirements.

       The latter generally adopts a cage rotor structure and obtains a low speed by increasing the number of poles,It is mainly operated in the state of large load and low speed,Can also be short-term or long-term operation in the blocked state. It can be divided into synchronous and asynchronous two, the current commonly used is the squirrel cage asynchronous motor, with low speed and large torque characteristics. Generally, it is often used in the textile industry, and its working principle and structure are the same as single-phase asynchronous motors, but because the resistance of the squirrel cage rotor is larger, its mechanical characteristics are softer.

       Expansion: In order to overcome the disadvantages caused by the use of brushes and commutators,70At the end of the decade, torque motor manufacturers developed brushless DC, and its principle and structure are the same as brushless DC motors.
