Problems solved by technology
[0004] Especially for the heating of the motor stator, it often occurs. Since the motor stator is in long-term rotation, not only is it easy to reduce the insulation due to its own circuit, and it will cause excessive heat after breakdown, but also cause insulation due to external factors. Decreased sex, exacerbated fever
[0005] However, when the existing inspection method is used to inspect the motor stator, it is generally only possible to check the local leakage of the motor. The problematic coil position in the motor stator makes the motor work a safety hazard and affects the safe operation of the motor

Description
technical field [0001] The invention relates to the technical field of motors, in particular to a safety detection device for motor testing and a detection and analysis method. Background technique [0002] The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machines. Common electromagnetic motors mainly include stator poles, Rotor (armature), commutator (commonly known as commutator), brushes, casing, bearings, etc., and during the operation of the motor, heat often occurs. [0003] After the motor heats up, the insulation temperature of the motor winding will rise, and the insulation reacts strongly to high temperature, which will accelerate aging and reduce the service life. If the temperature rises too high, the insulation will be carbonized, the insulation will...
