Abstract:
1. An electric motor, comprising: a. a stator having separately formed pole pieces and return path pieces mated together; b. field coils disposed on the pole pieces between the pole pieces and the return path pieces mated to the pole pieces; c. each field coil having an insulating sleeve over each portion of the field coil that is disposed between the pole piece on which the field coil is disposed and one of the return path pieces mated to that pole piece; d. a pliable adhesive strip disposed between a surface of each insulating sleeve and a surface of at least one of the pole piece and return path piece that abuts that surface of that insulating sleeve to take up clearances between the field coil having that insulating sleeve and that one of the pole piece and return path piece; and e. an armature in the stator.
