An encapsulated stator assembly includes a plurality of like laminations stacked in registration with one another. Each lamination contacts at least one adjacent lamination, but none of them are integrally connected in any way to any other lamination. A single covering layer partially encloses and maintains in registration the plurality of like laminations. At least one post with a deflectable head extends from the covering layer. A motor assembly having a rotor assembly coupled with the stator assembly partially encapsulated by a covering layer is mountable to a control circuit board by inserting the deflectable heads into an appropriate receptacle on the circuit board. The motor assembly is used to operate a fan assembly carried by a housing. The method of molding a covering layer over the plurality of laminations is also disclosed.

Insulated stator core with attachment features

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.
