Excitation Waveform Determination Device, Motor Drive Device, Excitation Waveform Determination Method, Motor Drive Method, And Program

Abstract: An excitation waveform determination device (100) sets an initial candidate solution group (IS) and a new candidate solution group (US) as one or more candidate groups for an excitation waveform on the basis of harmonic superimposition conditions (HC) that are information for identifying harmonics to be superimposed on the fundamental wave included in the excitation waveform, executes an electromagnetic field analysis to calculate electromagnetic forces generated in a stator (320) when candidate solutions included in the one or more set candidate solution groups for the excitation waveform are caused to flow through the motor (M), and determines the excitation waveform on the basis of results of executing the electromagnetic field analysis.
