| 摘要 |
The present invention relates to a system of controlling an induction electric motor (105), comprising an input unit (303) for receiving a command speed of high speed for the induction electric motor; a command voltage output unit for generating a command voltage for operating an inverter (104) according to the command speed and outputting the generated command voltage to the inverter; a control unit (301) for controlling the command voltage output unit (304, 305, 306) such that the command voltage output to the inverter is compared with an operation limiting voltage and the command voltage is corrected to fall within the operation limiting voltage, depending on a result of the comparison; and the inverter (104) for controlling the induction electric motor at a high speed depending on the corrected command voltage. |
