An Analysis of the Hysteresis Motor I - Analysis of the Idealized Machine

This paper presents an analysis of an idealized polyphase hysteresis machine. The distributed magnetic field within the machine is described in terms of dimensions and windings. A single-phase equivalent circuit is developed for the machine and expressions are given for the parameters of this equivalent circuit and for the machine torque. Improvement of power factor by reduction of stator voltage is discussed. Results predicted from the equivalent circuit are compared with experimental data obtained from a small hysteresis motor.
