Turn ratio of the capacitor motor

IN a previous paper
¹
the basic equations for the stator and rotor-winding currents of the capacitor motor were established in terms of certain coefficients which were functions of the fundamental constants of the machine. Application of these relations to establish the current loci was made to typical design data taken from earlier papers by Morrill,
²
and Puchstein and Lloyd,
³
based on a single value of the ratio of auxiliary-winding turns to main-winding turns. It is the purpose of this paper to extend the investigation to determine the effects upon current loci, and upon certain performance characteristics, of changing the turn ratio.
