Claims

[Claims for Utility Model Registration] A rotor that is rotatably provided with a field magnet, an armature that generates a rotating magnetic field with respect to the rotor, and excitation means that excites the armature. In a blower comprising a motor and an impeller rotatably fixed to a rotating shaft of the motor, an appropriate number of air holes for armature cooling are provided at predetermined positions of the rotor of the motor, and A blower characterized in that a vehicle is provided with an appropriate number of air holes so as not to overlap in the same direction as the air holes formed in the rotor of the motor.
