发明名称 APPARATUS AND METHOD OF USING THE STATOR COILS OF AN ELECTRIC MOTOR TO MAGNETIZE PERMANENT MAGNETS OF THE MOTOR ROTOR WHEN THE SPAN OF EACH STATOR COIL IS SMALLER THAN THE WIDTH OF EACH PERMANENT MAGNET POLE
摘要 An apparatus and its method of use enable magnetizing the permanent magnets of an electric motor rotor using the winding coils of the motor stator when the circumferential width of each rotor permanent magnet pole is larger than the circumferential width of each stator winding coil.
