  • Control device for alternating current motor
    Patent number: 6246209
    Abstract: The present invention relates to a control of an AC motor, and in particular to a control device for an AC motor which can prevent an overvoltage from being applied to the motor, and minimize voltage consumption of a reactor itself during the starting and accelerating operation of the motor, by restricting a sharp increase of a motor line voltage resulting from a high-speed switching of an inverter during a high-speed operation of the motor, and a voltage reflection phenomenon of input terminals of the motor generated due to non-matching of a characteristic impedance between a power line and the motor, by inserting the reactor having a bar shaped core between the inverter and the motor.
