Abstract
PURPOSE: To make it possible to start in a short time by means of a small-capacity inverter, by starting the motor by setting the output voltage and output frequency at fixed values and shifting the operation to normal when the number of revolutions has attained a proper value.
CONSTITUTION: Power is supplied to induction motor 6 through AC power source 1, rectifier 2, chopper 3 and inverter 4. At the time of starting, switching contacts 21, 23 are set at the positions opposite to those shown in the drawing, and a speed command is given from setter 22 at a fixed speed. A set value is given to the voltage control system by setter 25. When the motor is started and the number of revolutions exceeds the value set by setter 19, set value 25 is removed from the voltage control system. When the number of revolutions exceeds the value set by setter 20, the speed command is switched to the speed command of setter 7 and the operation is shifted to the range of normal rotational speed control.
