ABSTRACT:
A single-phase induction motor provides a plurality of serially connected main winding coils and a plurality of corresponding auxiliary winding coils each spaced in quadrature from a corresponding main winding coil. Each auxiliary winding coil is energized by the current induced in a serially connected pick-up coil located within a stator slot containing the quadrature main winding coil in response to the energization of the main winding coil for providing a starting torque to the rotor. Each auxiliary coil contains a first predetermined number of turns wound in a first direction within one stator slot and a second predetermined number of turns wound in a second direction located in an adjacent stator slot for increasing the resistance-to-reactance ratio. Each pick-up coil contains approximately one-half the turns of each auxiliary coil which, in turn, has a substantially lesser number of turns than each main coil.
