    • In a motor driving unit controlled by switching to/from PWM control from/to PAM control so that the maximum limit of motor speed can be increased and, at the same time, the unit can be operated at maximum efficiency during steady-state operation, the motor speed is controlled by maintaining the DC voltage command to the converter control circuit constant, but altering the conduction ratio command value to the inverter control circuit when the load to the motor is low, and by maintaining the conduction ratio command to the inverter control circuit constant, but altering the DC voltage command to the converter control circuit. There is a commutating phase control circuit that alters the commutating timing of the coil of the motor, and the motor is so controlled that the efficiency reaches the maximum limit during steady-state operation and the speed reaches the maximum limit during high-speed operation.
    • 在通过切换到/从PAM控制的PWM控制控制的电动机驱动单元中,可以增加电动机速度的最大极限,并且同时在稳态运行期间可以以最大的效率运行单元, 通过将转换器控制电路的直流电压指令保持恒定来控制电动机速度,但是当对电动机的负荷低时,将导通比指令值改变为变频器控制电路,并且通过保持与变频器控制的导通率指令 电路常数,但改变直流电压命令到转换器控制电路。 有一个整流相位控制电路,改变电动机线圈的整流时间,电机受到控制,使得在稳态运行期间效率达到最大极限,而高速运行时速度达到最大极限。
