Abstract
An electronically commutated motor has a printed circuit board with opposite sides and a heat dissipating means arranged in spaced apart relation at least in part in the path of at least some of the cooling circulated in the electronically commutated motor by the rotatable assembly thereof. A plurality of insulated gate transistors are located on the heat dissipating means in heat transfer relation therewith adjacent one opposite side of the printed circuit board and are operable to commutate power supplied to the winding stages of the electronically commutated motor. Other solid state components for controlling the conductivity of the insulated gate transistors are located on the other opposite side of the printed circuit board, and the insulated gate transistors and the other solid state components are connected in circuit relation with the printed circuit board.
