ROTOR, ELECTRIC MOTOR, FAN, AIR CONDITIONER, AND METHOD FOR MANUFACTURING ROTOR

A rotor (2) includes at least one first permanent magnet (21) and at least one second permanent magnet (22). The at least one first permanent magnet (21) forms part of an outer peripheral surface of the rotor (2) and is magnetized to have polar anisotropy. The at least one second permanent magnet (2...

More Information
Summary:A rotor (2) includes at least one first permanent magnet (21) and at least one second permanent magnet (22). The at least one first permanent magnet (21) forms part of an outer peripheral surface of the rotor (2) and is magnetized to have polar anisotropy. The at least one second permanent magnet (22) is adjacent to the at least one first permanent magnet (21) in a circumferential direction of the rotor (2) and has lower magnetic force than magnetic force of the at least one first permanent magnet (21).
