[0002] A torque arm refers to a component used to transmit moment or torque in a mechanical system. In a hollow shaft motor, the torque arm's function is to transmit the torque generated by the motor to an external device or load. Specifically, the torque arm of a hollow shaft motor performs the following functions: 1. Torque transmission: The hollow shaft motor transmits the torque generated by the motor to an external device or load through the torque arm, thereby driving these devices or loads to rotate or perform other mechanical actions. 2. Supporting rotating parts: The torque arm can also serve as a structural support for rotating parts, ensuring that the rotating parts remain stable and balanced during operation. 3. Adjusting torque transmission: By designing torque arms of different lengths or shapes, the torque transmission effect can be adjusted, allowing the hollow shaft motor to adapt to different work needs and load requirements. In general, the torque arm of a hollow shaft motor plays an important role in the entire motor system, such as transmitting torque, supporting rotating parts, and adjusting torque transmission. It is a key component to ensure the normal operation of the motor and the effective transmission of power.
