摘要：
This paper proposes bevelling magnet edges that can reduce iron losses in permanent magnet (PM) machines. The maximum flux density and time rate change of flux density in teeth and yoke are deduced, respectively, considering a random angle of bevelling magnet edges. The analytic models of the average eddy current and hysteresis loss in teeth and yoke are presented respectively. The torque ratio of bevelling 75° and right-angle magnet is 0.983, whereas the ratio of PM material required between two cases is 0.971. Experimental results were proposed to verify the analytic model of total iron losses. © Institution of Engineers Australia, 2010.
