Abstract
A motor has a sufficient heat dissipation function even when a non-magnetic material having low thermal conductivity is used for a shaft of a motor using a consequent pole rotor. A motor includes: a stator; a consequent pole rotor including a rotor core and a magnet; a casing housing the stator and the rotor; a shaft including a non-magnetic material and fixed to the rotor; and heat dissipation blades that are a first heat dissipation promoting means that rotates with the shaft. This promotes heat dissipation through a heat dissipation path from an inside of the motor through the shaft, preventing problems due to overheat in the motor.
