Two pole electric motor constructions with stator winding encircling the rotor and method of assembling same

A construction for a two-pole motor, comprising a main stator section provided with a central cylindrical opening;

• a rotor within said cylindrical opening mounted for rotation about a motor axis, said main stator section defining lateral stator portions on opposite sides of said cylindrical opening and generally flat top and bottom stator surfaces above and below said cylindrical opening, each of said top and bottom stator surfaces including a coil bearing surface generally coextensive with said cylindrical opening and yoke-abutting surfaces, on each side of said coil bearing surfaces, and generally coextensive with said lateral stator portions;
• stator windings defining an opening configured and dimensioned to extend over said lateral stator portions with clearance and moved into abutment against said coil bearing surfaces, said stator windings encircling said rotor;
• stop means on said coil bearing surfaces for limiting movement of said stator coils from one side of the motor axis to the other side thereof while aligning said stator coils axially with the rotor in overlapping relationship therewith;
• and generally U-shaped upper and lower yokes each having a pair of lateral yoke arms and a transverse yoke portion, said U-shaped yokes being dimensioned to maintain said stator coils on said coil bearing surfaces in overlapping relationship with said rotor.
