PURPOSE:To reduce the size and the cost by making rectifier, one smoothing capacitor and one CPU common for controlling the position, speed and current of a plurality of motors individually. CONSTITUTION:Two inverters 21 and 22 are installed at the output side of a smoothing capacitor 6. CT's 31 and 32, motors 41 and 42 and PG's 51 and 52 are also installed at the output side of the smoothing capacitor 6 so that they may correspond to the inverters 21 and 22 respectively. Due to this configuration, the inverters 21 and 22 are individually controlled by ACR's 13A and 13B respectively. There is only one CPU 11 for the two ACR's 13A and 13B. In other words, one and the same CPU 11 is made common for controlling and operating the position, speed or torque of each motor individually. By this method, the size and the cost can be reduced. |
