MOTOR DRIVE CONTROL DEVICE

A motor drive control device 500 is a device which drives and controls a permanent magnet synchronous motor 100 in which each phase is independently controlled, and includes a 0-axis current calculation unit 305 which calculates and outputs a 0-axis current iz on the basis of a motor current; a 0-ax...

More Information
Summary:A motor drive control device 500 is a device which drives and controls a permanent magnet synchronous motor 100 in which each phase is independently controlled, and includes a 0-axis current calculation unit 305 which calculates and outputs a 0-axis current iz on the basis of a motor current; a 0-axis current determination unit 306 which compares and determines a reference 0-axis current value izs which is the 0-axis current value when the temperature of a permanent magnet provided in the permanent magnet synchronous motor 100 is a reference temperature with the calculated 0-axis current iz; and a switching signal generation unit 301 which drives and controls inverters 210a, 210b, and 210c on the basis of the result of comparison determination of the 0-axis current determination unit 306.
