An Analysis of the Hysteresis Motor II-The Circumferential-Flux Machine

Part I of this paper presented an analysis of an idealized polyphase hysteresis machine having a radial-flux type of rotor. In this Part II, a hysteresis machine with a circumferential-flux type of rotor is analyzed. Using a rectangular loop approximation to the B-H characteristic of the hysteresis material, the flux density distribution in the machine is found and an equivalent circuit is developed. An improved model of the B-H loop is then used, and two approximate analyses are developed for this improved representation of the machine.
