To measure performance impact parameters of a motor while capturing currents of two phase coils with a simple circuit configuration.SOLUTION: A control circuit unit 4 of a motor drive controller 1 performs an arithmetic processing for control of a motor 20 during a period of each half of two consecutive PWM periods, and during the rest two periods of each half of the two consecutive PWM periods, in which the arithmetic processing for control is not performed, acquires the detection results of first and second currents, which are the currents of two phase coils among three phase coils, from a current detection circuit 2c and the detection result of performance impact parameters from a performance impact parameter detection unit.SELECTED DRAWING: Figure 1 【課題】簡易な回路構成でありながら、２相のコイルの電流を取り込みつつ、モータの性能影響パラメータを測定する。【解決手段】モータ駆動制御装置１の制御回路部４は、連続する２つのＰＷＭ周期のそれぞれの半周期においてモータ２０の制御用演算処理を実行し、連続する２つのＰＷＭ周期における制御用演算処理を実行していない残りの２つの半周期に、電流検出回路２ｃからの３相のコイルのうちの２相のコイルの電流である第１の電流の検出結果及び第２の電流の検出結果と、性能影響パラメータ検出部からの性能影響パラメータの検出結果と、を取得する。【選択図】図１
