Title:
MOTOR CONTROL DEVICE AND MOTOR CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2013/129230
Kind Code:
A1
Abstract:
This motor control device comprises: a boost converter circuit (30) for boosting DC voltage; an inverter (40) for generating driving pulses for a motor (50) from the DC voltage output from the boost converter circuit (30); and a control unit (60) for presetting a setting value (Id_hold) obtained by multiplying an intermediate current threshold factor (α) to a setting value (Id-max), controlling the pulse width of driving pulses for the inverter (40) according to the speed deviation, controlling the d-axis current of the motor (50) according to the speed deviation so that the pulse width of driving pulses for the inverter (40) does not exceed a threshold, and controlling the DC voltage of the boost converter circuit (30) according to the speed deviation so that the d-axis current of the motor (50) does not exceed the setting value (Id_hold).
