概要	© 2018, The Minerals, Metals & Materials Society. In this paper, the increment factor of the iron loss by inverter excitation compared with sine wave excitation was clarified using the magnetic hysteresis curve, and change in the parameter which can be understood intuitively was explained. When α (rate of hysteresis curve between the inverter excitation and the sine wave excitation), β (width of the closed loop using inverter excitation around 0 T) and γ (width of the open loop using the inverter excitation around 0.8 T) are increased by the switching operation of the inverter excitation, they increase the area of the hysteresis curve and increase the iron loss compared with the sine wave excitation. On the other hand, the increase factor of the iron loss by the inverter excitation was clarified, and explanation which can be understood intuitively was given. The low modulation factor, the low career frequency, and the high VDC of the inverter are made to increase the factors such as α and β, and increase the area of the magnetic hysteresis curves, and this causes incremental iron loss. Furthermore, α and β are made to fluctuate by the control method of the motor drive using the inverter. That is, the change of the inverter parameters fluctuates the iron loss due to a tradeoff.
