In particular, the variable speed type switched reluctance motor generates continuous torque with the help of the sensor which detects the position of the converter and the rotor using the power semiconductor, and it is easy to control according to the performance required in each application field.

Generally, a sensing module, such as a sensing magnet for indicating the position of the rotor and a Hall sensor for sensing the sensing module, is disposed inside the motor, If an error occurs in the sensing module due to the environment, the motor should be discarded or disassembled and repaired.

Particularly, there is a problem in that the disassembling operation of the bonded bearings is difficult, and the parts damaged during disassembly must be replaced, resulting in a time and economic loss.
