More Information
Summary:The invention belongs to the field of multi-pole motor magnetizing, and discloses an overall magnetizing method and device for a multi-pole motor, and the method comprises the steps: arranging at least one magnetizing coil at the periphery of a motor rotor in the circumferential direction, and enabling each magnetizing coil to cover a plurality of continuous permanent magnetic poles, setting each magnetic pole in the magnetizing interval covered by at least one magnetizing coil as a target permanent magnetic pole or a non-target permanent magnetic pole, and arranging a shielding plate on the outer side of the non-target permanent magnetic pole; pulse current is introduced into the magnetizing coil to magnetize the target permanent magnetic pole, and meanwhile, eddy current is induced in the shielding plate to generate an additional magnetic field to counteract an original magnetizing magnetic field, so that the magnetic state of a non-target permanent magnetic pole is kept unchanged; and changing the relative
