Document Type and Number:
Japanese Patent JP5807847
Kind Code:
B2
Abstract:
A control device for controlling a three phase AC motor with an inverter includes: a current acquisition device for a current of the motor; a rotation angle acquisition device for a rotation angle of the motor; a current estimation device for a current estimated value; a first voltage command value operation device for a first voltage command value; a voltage command reference value operation device for a voltage command reference value; a second voltage command value operation device for a second voltage command value; a control mode switching device for first and second control modes generating a drive signal of the inverter based on the first and second voltage command value, respectively; and a number-of-revolutions operation device. When the revolution number is more than a threshold, the first control mode is selected. When the revolution number is not more than the threshold, the second control mode is selected.
