Abstract

PURPOSE:To effectively enable to pull in a plurality of motor to the inverter drive by controlling the pull in timing of the respective motors to the inverter driving. CONSTITUTION:Motor frequency fm is obtained by detecting the motor frequencies fm1, fm2, fm3 via the detecting transformers 700a, 700b, 700c of the motor residual voltage frequencies from the power lines of the motors 500a, 500b, 500c and selecting one of them via change-over switches 800a, 800b, 800c respectively. Since the respective motors are sequentially pulled in accordance with the prescribed time sequence, the rotating speed of the motors are approximately equal at the starting time of the inverter, and accordingly the overcurrent caused by the speed difference can be suppressed to remarkably small value.
