ABSTRACT:
A unitary fan and drive assembly is formed by means of a disc-shaped plate having a set of fan blades disposed along the periphery of the plate. A compact shape is provided by forming the drive with a rotatable member that is nested within a central recess of the plate. An electric drive is conveniently implemented by an electric motor wherein the rotatable motor member has fan blades disposed along the periphery and wherein the stationary motor member includes a low-profile annular array enclosing an assembly for electrically energizing the motor.
