要約(英語): To estimate iron loss in interior permanent magnet (IPM) motors driven by PWM inverters accurately, 1-dimensional finite-element analyses for a silicon steel sheet in the thickness direction considering hysteretic property and skin effect were proposed. However, the method cannot directly consider so-called excess loss. To express the excess loss, the eddy current loss correction factor is introduced into the method and the basic property of the factor under sinusoidal excitation has been investigated. In this paper, we investigate the property of the factor for plastic deformation assumed for press working. Finally, we apply the iron loss estimation method to the IPM motors and discuss the contribution of eddy-current, hysteresis and excess losses.
