On the Induction Motor under Cyclical Operation

Abstract

In Chapter I the interaction of the fly-wheel and the induction motor under cyclically varying load of any given form was considered. The motion of the induction motor during the whole period has been determined, and formulae governing the proportion of the fly-wheel and the motor have been developed. The general formulae have been applied to some special cases of practical importance. Since when the resisting torque of an induction motor under cyclical operation is given, we can in general find the manner of variation of the torque imposed upon the motor, whether the rotor has or has not a fly-wheel, in Chapter II formulae for determining the capacity of the induction motor under cyclical operation of any form of load rated for continuous running have been developed. The general formulae have been applied to some special cases. In conclusion the author wishes to express sincere thanks to Prof. E. Aoyagi, at whose suggestion this work has been undertaken, and to Prof K. Ogura for his kind suggestions.
