Abstract
A shaded pole motor having a shading loop or band that fits with an interference fit adjacent the field plate stack of laminations at the location thereon adjacent the field winding, but having ample clearance space from the stack adjacent the ends of the stack; whereby an epoxy coating can be used to insulate the stack and shading loop from the windings. The shading loop adjacent the ends of the stack further projects well beyond the ends of the stack distances comparable to the breadth of the winding, whereby the winding is mechanically constrained on the stack in part by the shading loop.
