  • Patent number: 6075304
    Abstract: A stator has a lamination stack with a first electrically insulating layer and coil guides formed of high flow thermoplastic synthetic resin simultaneously insert-molded thereon. A coil is wound onto the stack and over the electrically insulating layer and the coil guides, and a second electrically insulating layer is molded over the coil to encase the coil. The second electrically insulating layer is formed of the high flow thermoplastic synthetic resin by injection molding. The method for producing the stator includes inserting the lamination stack into a first molding tool installed on an injection molding machine and injection molding onto the lamination stack the first insulation layer and the coil winding guides wherein the first insulation layer coats at least top and bottom surfaces and surfaces of slots of the lamination stack with thin resin skin insulation. The coil is then wound using insulated thin copper wire.
