Zusammenfassung:To provide a generator starting method for an integrated starter generator (motor generator).SOLUTION: A generator starting method for a motor generator (2) drives the motor generator (2) without using a position sensor to start an engine (3) includes the following steps of: (a) applying a drive current (Idr, Idr1-Idr3) with a frequency and an amplitude to drive the motor generator (2) to reversely rotate in a speed open-loop control mode and acquiring load information (Vi) according to a drive voltage (Vdr, Vdr1-Vdr3) and the drive current (Idr, Idr1-Idr3) of the motor generator (2); (b) confirming whether the load information (Vi) has met a heavy load condition; (c) stopping reversely rotating the motor generator (2) when it is determined that the load information (Vi) has met the heavy load condition; and (d) forwardly rotating the motor generator (2) to drive the engine (3) to start.SELECTED DRAWING: Figure 4 【課題】統合型スタータージェネレーター(電動発電機)の発電機始動方法を提供する。【解決手段】位置センサレスの電動発電機(2)を駆動することによってエンジン(3)を始動させる電動発電機(2)の発電機始動方法であって、速度開ループ制御モードにおいて周波数と振幅を有する駆動電流(Idr、Idr1~Idr3)を入力して電動発電機(2)が反転するように駆動し、電動発電機(2)の駆動電圧(Vdr、Vdr1~Vdr3)と駆動電流(Idr、Idr1~Idr3)に基づいて負荷情報(Vi)を取得するステップ(a)と、負荷情報(Vi)が重負荷条件を満たしたか否かを確認するステップ(b)と、負荷情報(Vi)が重負荷条件を満たしたと判断した場合、電動発電機(2)の反転を停止させるステップ(c)と、電動発電機(2)を正転させてエンジン(3)を始動させるステップ(d)と、を含む。【選択図】図4
