摘要： PURPOSE: A method and a device are provided to reduce time required to reach a rotational speed corresponding to a normal operation, by feeding an over-voltage to an induction motor. CONSTITUTION: A method comprises a first step of accelerating an induction motor, by permitting an inverter to increase an output frequency thereof until the output frequency reaches a frequency level corresponding to a normal operation, and generating an output for increasing an AC voltage to an over-voltage state in correspondence to the output frequency; and a second step of lowering the AC voltage to a voltage level corresponding to the normal operation when the rotational speed of the induction motor has achieved a predetermined speed.

摘要： A control method of an induction motor suitable for an induction motor requiring a very large driving torque at the time of starting or acceleration of a textile machine, or the like, wherein a variable voltage variable frequency (VVVF) inverter (8) supplying power to the primary winding of the induction motor (9) increases its output voltage and output frequency after start while keeping the output current from the inverter lower than a specified current limit level, lowers only the output voltage of the VVVF inverter (8) down to a specified voltage set level after finishing acceleration of the induction motor (9), and then supplies an AC voltage corresponding to the frequency set level and the voltage set level continuously from the VVVF inverter (8) to the induction motor (9).
