the Hysteresis Motor.

Significant contributions to the theory of the hysteresis motor are briefly reviewed, and certain shortcomings of the present theory indicated. A novel approach to calculating the asynchronous torque, based on a surface integral instead of the customary volume integral, is presented. An experimental hysteresis motor, and several methods of testing the theory, are described, and deviations from the predicted performance examined with a view to establishing the magnitude of the various losses.
