To provide a rotary machine control device capable of simultaneously driving a multi-phase rotary machine and a plurality of DC rotary machines.SOLUTION: An ECU10 (rotary machine control device) is capable of driving a three-phase motor 800 and a plurality of DC motors 710 and 720. A first terminal T1 which is one end of the plurality of DC motors 710 and 720 is connected to a phase current path of the same one phase of a three-phase coil set 801. An inverter (multi-phase power converter) 601 converts DC power of a power source Bt1 into three-phase AC power and applies a voltage to each phase coil of the three-phase coil set 801. DC motor switches MU1H/L and MU2H/L are constituted of high-potential side and low-potential-side switches which are connected in series via DC motor terminals M1 and M2. The DC motor terminals M1 and M2 are connected to a second terminal T2 of the DC motor 710, 720. The DC motor switches MU1H/L and MU2H/L vary voltages Vm1 and Vm2 of the DC motor terminals M1 and M2 by switching.SELECTED DRAWING: Figure 5

    【課題】多相回転機及び複数の直流回転機を同時に駆動可能な回転機制御装置を提供する。【解決手段】ECU10(回転機制御装置)は、三相モータ800及び複数の直流モータ710、720を駆動可能である。複数の直流モータ710、720の一端である第1端子T1は、三相巻線組801の同一の一相の相電流経路に接続されている。インバータ(多相電力変換器)601は、電源Bt1の直流電力を三相交流電力に変換し、三相巻線組801の各相巻線に電圧を印加する。直流モータ用スイッチMU1H/L、MU2H/Lは、直流モータ端子M1、M2を介して直列接続された高電位側及び低電位側のスイッチにより構成される。直流モータ端子M1、M2は、直流モータ710、720の第2端子T2に接続されている。直流モータ用スイッチMU1H/L、MU2H/Lは、スイッチングにより直流モータ端子M1、M2の電圧Vm1、Vm2を可変とする。【選択図】図5
