[0002] In the production and processing of motors, it is necessary to weld the rotor winding of the motor. The rotor winding consists of guide bars placed in the rotor core slots and copper rings at both ends. For high-power motors, copper guide bars are often inserted into the rotor core slots, and then copper rings are welded at both ends of the guide bars.

The current generates an alternating electromagnetic field, which induces eddy current in the copper ring and heats the copper ring. After a period of time, the required temperature is reached, the solder melts and fills the weld, and after cooling, the copper ring and the guide bar are tightly welded together to meet the process requirements of motor manufacturing.

[0005] When welding copper rings of different thicknesses, workers are required to measure the installation position of the temperature sensor according to the thickness of the copper ring, which makes the installation of the temperature sensor inconvenient and affects the welding efficiency of the rotor copper ring.
