1. A method of making an electric motor with the stator winding inside a slotless cylindrical stator shell comprising the steps of:
- forming a slotless cylindrical stator shell of magnetic material;
creating a generally cylindrical support with a reduced diameter portion at one end;
forming the winding around said support from preformed coils such thatthe coil and turns at one end of said support flare inwardly and extend adjacent said reduced diameter portion, andthe coil end turns at the other end of said support flare outwardly;
inserting said winding into said cylindrical stator shell starting with the inwardly flared end coils while the winding is supported by said support;
impregnating said winding with a resin to secure said winding inside said stator shell; and
removing said support from the winding through said end having said outwardly flared end coils.
