“…We measured loss in a real motor and compared to verify the loss calculation by the permeance method also works for real drive systems. While IPMSMs are often driven by inverters, the loss originates from voltage harmonics has to be considered when carrier frequency is low [3,4]. However, this loss decreases with higher carrier frequency.…”

“…However, this loss decreases with higher carrier frequency. Also, as compared to the two-level inverters, harmonic components in three-level inverters can be suppressed even without a carrier frequency as high as that of the two-level inverters [4], and moreover the related inverter's switching loss can be reduced. In this section, we calculate loss assuming that IPMSM is driven by a three-level inverter and loss caused by carrier harmonics are negligibly small.…”

SUMMARY In this study, the lowest loss point is calculated using the permeance method when the machine parameters of the interior permanent magnet synchronous motor are changed. Using the proposed method, the motor loss is easily calculated compared to the conventional method. The periodic change in the magnetic resistance in the air‐gap according to the rotation of the rotor does not need to be considered because the magnetic equivalent circuits of the rotor and stator are separated. In this study, the motor loss is calculated by the proposed method and a finite element method (FEM). As a result, the error in the calculation results between the permeance method and the FEM is 2.9%. On the other hand, the motor losses are calculated by the permeance method when some machine parameters are changed. As a result, these results agree in principle with those of the FEM. Therefore, the validity of the proposed method is confirmed. In addition, the method for motor design is considered in terms of the loss.
