ABSTRACT:
A method for winding stator coils of a single phase induction electromotor comprising winding a starting coil, avoiding winding of the starting coil about selected slots, moving an outer coil pitch to form coil overlapping slots adjacent to the selected unused slots for eliminating unused teeth, whereby the starting coil overlaps the starting coil in the selected slots disposed in a starting winding with a 90.degree. electric angle for increasing the starting torque and promoting the operation efficiency of the electromotor.
