Modeling and optimum design of disk-type hysteresis motors

In this paper, calculation of electrical equivalent circuit parameters versus design parameters of high frequency disk-type hysteresis motors are presented in details for steady state operating conditions. It is demonstrated that some of the equivalent circuit parameters alter significantly with input voltage and for different operating conditions. Therefore an equivalent circuit with fixed elements may give an inaccurate prediction of the steady state performance of a machine in many circumstances. Furthermore in this paper for a disk-type hysteresis motor which is designed and manufactured by use of variable parameter model, a sensitivity analysis is presented and influences of some design parameters on machine performances are discussed.
