Axial flux permanent magnet motor

An axial flux permanent magnet motor comprising:

• a shaft;
• a rotor spaced apart from the shaft in an axial direction by a predetermined distance and comprising a pair of first and second extension members extending in a radial direction, the rotor being rotatably mounted on the shaft;
• first and second magnet parts respectively disposed on the first and second extension members to face each other in the axial direction, the first and second magnet parts having N poles and S poles, alternately disposed in a circumferential direction;
• a support member extending from the shaft in the radial direction, the support member being disposed between the first and second extension members in the axial direction;
• and
• an electromagnet part disposed on the support member to face the first and second magnet parts in the axial direction,
• wherein an axial distance between facing surfaces of the first and second magnet parts and the electromagnet part repeatedly changes in the circumferential direction.

An axial flux permanent magnet motor comprising:

• a stator member;
• a rotor member rotatably mounted on the stator member;
• a magnet part disposed on the rotor member to face an axial direction, the magnet part having N poles and S poles, alternately disposed in a circumferential direction;
• and
• an electromagnet part disposed on the stator member to face the magnet part in the axial direction,
• wherein an axial distance between facing surfaces of the magnet part and the electromagnet part repeatedly changes in the circumferential direction.
