METHOD FOR MANUFACTURING MOTOR AND STATOR

WIPO Patent Application WO/2017/094689

A1

A motor comprises an A-phase stator unit, a B-phase stator unit, and a rotor. The A-phase stator unit and the B-phase stator unit respectively contain a coil unit and a pair of stator cores, each pair of stator cores having a plurality of claw-shaped magnetic poles. The rotor comprises at least two permanent magnets facing the claw-shaped magnetic poles of the A-phase stator unit and the claw-shaped magnetic poles of the B-phase stator unit, respectively. The A-phase stator unit and the B-phase stator unit are provided side by side in the axial direction, displaced from one another by a prescribed electrical angle. The two permanent magnets are arranged side by side in the axial direction, displaced from one another by a prescribed electrical angle. The direction of displacement between the A-phase stator unit and the B-phase stator unit is the opposite of the direction of displacement between the two permanent magnets.
