摘要

To provide a power supply voltage waveform calculation method and a circuit coupling magnetic field analysis method for calculating a steady solution at a speed higher than a conventional method.SOLUTION: An electromagnetic apparatus of a motor or the like using a coil current accepts input of an initial value of a desired coil current waveform to execute a magnetic field analysis of the electromagnetic device, and calculates a power supply voltage waveform derived from a magnetic vector potential obtained by the analysis. Then, the electromagnetic apparatus uses a basic waveform component of the calculated power supply voltage waveform to perform a circuit coupling magnetic field analysis.SELECTED DRAWING: Figure 1
