    摘要: A current detection device used for a plurality of rotating electric machines is provided. The rotating electric machines are supplied with a composite current containing a plurality of frequency components from an single inverter and the frequency is set in response to the rotational angular velocity of one rotating electric machine. The current detection device is provided with a current sensor which detects only current components at a single frequency in the composite current. The current sensor detects the currents in a set of supply lines, the supply lines of which being collected and passing through the current sensor so that the current components of the frequency different from the single frequency cancel out to zero in the set of supply lines.

    摘要: A motor/generator comprises a stator (2) having plural coils (C1-C14), and plural rotors (3, 4) disposed coaxially with the above-mentioned stator and driven by a compound current. The phase difference between the currents (70, 71) driving the rotors (3, 4) is arranged to be other than 180 degrees. Thereby, the utilization factor of the voltage of the direct current power supply (10) is improved.
