Abstract: The stator is one of the main components of the motor. When machining, the winding direction of a slot is opposite, which is called reverse embedding. Aiming at the bad phenomenon of anti embedding, a detection system based on current magnetic effect is designed. By applying a constant current source to the stator coil to generate a magnetic field, the hall sensor reads the magnetic field intensity of the coil, and then the software algorithm calculates the magnetic pole generated by the coil, and determines the anti embedding position according to the magnetic pole. The experimental results show that the system can accurately judge the defective products.
