TLDR
In this article, the double revolving field theory is used to analyze the capacitor motor operation, which is an extension of the double rotating field theory to the usual single-phase induction motor.Abstract:
Analyses of the capacitor motor operation date back to the 1920's, a pioneer effort being that of Bruderlin1 in Europe Work by Bloch,2 Biermanns,3 and others antedates that of Morrill4 in this country whose analysis has been widely used All of these have been based on the double revolving field theory, being extensions of that theory to the usual single-phase induction motorread more

A Very Rapid Prediction of IM Performance Combining Analytical and Finite-Element Analysis
TL;DR: In this article, an analysis procedure of the induction motor is presented that combines a set of finite-element simulations with an analytical model. But the choice of specific quantities releases the results from the actual motor length and extends them to any motor adopting the same lamination and winding distribution.

Revolving-field polygon technique for performance prediction of single-phase induction motors
C.B. Rasmussen,T.J.E. Miller +1 more
TL;DR: In this article, a new analytical technique for improving the performance prediction of single-phase induction motors, especially capacitor motors, is presented, which uses the split-phase motor electrical equivalent circuit analysis together with electrical and magnetic parameters whose variation is computed from the equivalent balanced polyphase motor, so that the same magnetic circuit analysis can be used for both.

An Analysis or Unexcited Synchronous Capacitor Motors
TL;DR: In this paper, the authors deduce from these theories a comprehensive representation of the capacitor-reluctance motor from which the motor characteristics, such as the starting torque, synchronous pull-out torque, torque angle, efficiency and so forth, can be calculated readily with useful accuracy.

Analysis of Unsymmetrical Machines
Waldo V. Lyon,Charles Kingsley +1 more
TL;DR: In this paper, the method of symmetrical components, which is so useful in the analysis of symmetrically wound polyphase a-c machines, can be extended readily to analysis of unsymmetrical 2 phase induction machines, such as the capacitor or split phase motor in which the windings are not in space quadrature.

The cross-field theory of alternatingcurrent machines
TL;DR: A businesslike and accurate way of obtaining the characteristics of an a-c motor was presented by West as discussed by the authors, which was especially intended for use by engineers having to do with large numbers of motors.
