Title:

MOTOR, AND AIR CONDITIONER IN WHICH SAME IS USED

Document Type and Number:

WIPO Patent Application WO/2021/024338

Kind Code:

A1

Abstract:

The purpose of the present invention is to obtain a motor having an adequate heat dissipation function even when a non-magnetic material having a low thermal conductivity is applied in the shaft of the motor, in which a consequent-pole-type rotor is used. A motor 1 provided with: a stator; a consequent-pole-type rotor configured from a rotor and a magnet; a casing for accommodating the stator and the rotor; a shaft 8 that is formed from a non-magnetic material and that is fixed to the rotor; and heat dissipation fins 24 serving as a first heat dissipation acceleration means that rotates together with the shaft 8. Dissipation of heat from a heat dissipation pathway extending from the interior of the motor 1 through the shaft 8 is thereby accelerated and defects resulting from overheating in the motor 1 are prevented.
