1. A method of making an electric motor, comprising:
- a. forming field coils to a predetermined shape;
b. forming pole pieces and return path pieces;
c. placing an insulating sleeve over each portion of the field coil that will be disposed between one of the pole pieces and one of the return path pieces mated to that pole piece and after forming the field coil to the predetermined shape;
d. after step c, placing the field coils with the insulating sleeves thereon on the pole pieces;
e. mating the pole pieces and return path pieces after placing the field coils on the pole pieces to form a stator; and
f. placing an armature in the stator.

Abstract
An electric motor has a field assembly, such as a stator, for a dynamoelectric machine has field coils that are wound to a net shape. Lead wires are brought out from the ends of each field coil. The field coils are insulated with insulating sleeves or insulating slot liners. The field coils are assembled with stator core pieces, such as pole pieces and return path pieces, into the stator. The stator core pieces are formed prior to being assembled with the field coils. In an aspect of the invention, the pole pieces and return path pieces are separately formed and then assembled together with the field coils, which have also been separately formed.
