ABSTRACT: "HALF-PITCH CAPACITOR INDUCTION MOTOR" A balanced, half-pitch capacitor induction motor having a stator core member with equally spaced teeth equal in number to twice the number of motor poles and with the inner ends of the teeth having equal angular extent, and a squirrel cage rotor member. The main field winding comprises serially connected coils equal in number to the number of motor poles respectively embracing alternate, consecutive ones of the teeth and being adapted to be connected across a single phase source of alter- nating current. An auxiliary field winding comprises serially connected coils embracing consecutive teeth intermediate the teeth having the main winding coils thereon, the auxiliary winding coils being serially connected with a phase-displacing capacitor across the serially connected main winding coils. The main and auxiliary windings have equal ampere turns and equal pitch thereby providing a balanced, half-pitch, two phase motor winding. The rotor member has its squirrel cage bars spiraled by one-tenth of a full turn, i.e., two pole pitches of the 5th harmonic or 36° to eliminate the fifth harmonic in the speed torque curve.
