ABSTRACT:
The control circuitry of a brushless blower motor is mounted on the stator of the motor and is cooled during operation of the blower by a portion of the air moved by the blower. A rotor cup member which covers and protects the control circuitry has at least a pair of radially displaced openings formed therein, and air is conveyed through the openings due to an air pressure differential therebetween created by the movement of air by the blower.
