In the motor having a gap passage, the rotor side member is provided with a blower fin on a surface facing the stator side member in the gap passage portion for sucking air from outside the motor into the inside of the motor. Also, a motor characterized in that an air exhaust port is formed for discharging air sucked into the motor by the blower fin to the outside of the motor.
