The magnetic pole detection part is arranged around the periphery of the rotor assembly. When detecting the polarity, each group of polarity detection components detects the polarity of the adjacent group of magnetic steel. If the polarity of the adjacent group of magnetic steel is opposite, the polarity detection component has no feedback action. If the polarity of the adjacent group of magnetic steel is the same, the polarity detection component sends a feedback signal to guide the staff to check the group of magnetic steel to check the problem of the same polarity. Through the application, the polarity of the rotor assembly can be detected, and the bad product rotor assembly can be prevented from entering the assembly production line to cause unnecessary influence on the motor product.
