Theory of hysteresis-motor torque

Wayne J. Morrill (General Electric Company, Fort Wayne, Ind.): Professor Teare has made an important contribution to the theory of hysteresis motors. His work outlines a method for approaching the problem of predetermining hysteresis-motor torque, and the data and conclusions given in his paper should be of considerable value to those actually designing such motors. I think it is no discredit to Professor Teare´s work to say that a thorough analysis of all the aspects of hysteresis-motor performance has merely received a good start and Professor Teare´s paper leaves open considerable opportunity for further investigation. It is to be hoped that further efforts, extending Professor Teare´s work, will be forthcoming at future meetings of the Institute.
