Capacitor motors with windings not in quadrature

Quite often the design of a split phase induction motor is such that the so-called quadrature winding is displaced at some angle other than 90 degrees from the main winding, in which event the motor behaves differently when run in opposite directions. It is the purpose of this paper to indicate a method by which the designer can predict the performance of such a motor. While the emphasis is placed upon the capacitor motor, the treatment is applicable also to motors of other types.
