Abstract:

A pole cap insulator is used in a field assembly of a motor having a cylindrical motor frame where the field assembly includes a winding having a central opening therein, and a pole member having a base portion with side surfaces and top and bottom surfaces. The pole cap insulator includes a generally rectangular body portion having a back edge disposed proximal the motor frame, and side boundaries disposed opposite each other. The body portion has a radially inwardly facing edge disposed opposite the back edge and tapered tip portions outwardly extending from opposite side boundaries cooperating with the radially inwardly facing edge to form a curved edge corresponding to a curved contour of the pole member. Also included are integrally formed side walls depending from the side boundaries of the body portion configured to engage a portion of the side surfaces of the pole member such that the body portion is retained on the top and bottom surfaces of the base portion so as to insulate the winding from the base portion when the base portion is received through the central opening of the winding.
