Abstract :
Equations developed to study the behaviour of hysteresis motors require some representation of the ferromagnetic hysteresis nonlinearity. In this paper, a method of representing hysteresis, which includes the effect of minor loops, is described and included in a computer solution to find the motor airgap field. The work has been done using circumferential-flux motors, but the method can also be applied to radial-flux motors. Terminal voltage/current characteristics from the computer model show the same overall behaviour as experimental results, and agreement is also found between the computed and experimental airgap flux-density waveforms. Possible improvements in the digital model are indicated.
