Compared wiht other synchronous motors, it is well known that the pull-out torque of the hysteresis motor is very decreased by the influence of the space higher harmonics. Two kinds of space harmonics exists in the motor. One of them (ΔH: constant) which is produced in the m. m. f., is due to the stator winding arrangement. The other (ΔB: constant) which is produced in the fluxdensity, is due to non-uniformity of the permeance in the air gap. The analysis due to the equivalent circuit of the hysteresis motor considering two kinds of the space harmonics has not been reported until now.In this paper, we derive the equivalent circuit considering influence of two kinds of the space harmonics. And, it is shown that the agreement between the calculated and the experimented values is comparatively good. Finally, we will make clear quantitativel influence of each harmonicto the pull-out torque.
