More Information
Summary:An arithmetic method by a computer according to the present embodiment includes model generating, execution processing, and electromagnetic interference noise generating. The model generating generates a model including a circuit model configured by a plurality of element models connected to each other and a motor model driven by the circuit model. The execution processing computes a motor current of the motor model generated in each of first calculating steps over time by using information on electrical characteristics of each element model. The electromagnetic interference noise generating generates electromagnetic interference noise in accordance with a frequency at a predetermined measurement point in the model in each of predetermined time segments in a measurement period, and generates an electromagnetic interference noise level at each frequency in the measurement period based on an electromagnetic interference noise level in accordance with the frequency in each of the time segments.
