A low profile motorized impeller assembly is provided for use in an air moving blower product. The assembly has a motor mounting base onto which a stator is fixedly attached. An impeller having a plurality of vanes has a ring-magnet rotor integrated therein. A pair of bearings are received in a beating receiving boss in the impeller, and a shaft which is fixedly attached to the motor mounting base is received therein. A plurality of permanent magnets are mounted on the motor mounting base between the arms of the stator so that when the windings of the stator are de-energized the permanent magnets attract the poles of the ring magnet to an offset position.
