Abstract
The electric motor disclosed in the specification has an encapsulated stator which includes inner and outer annular composite layers each having a radial flange joined to an end of the other layer by chemical welds, an array of laterally adjacent circular laminations and windings in axially extending slots in the laminations adjacent to the inner composite layers, and a metal band surrounding the laminations, along with encapsulating resin filling the space between the inner an outer layers. The motor also includes an encapsulated rotor having a similar structure, but with magnets inserted in axially extending slots in the laminations adjacent to the outer composite layer and a metal band disposed between the inner annular composite layer and the laminations.
