MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD

WIPO Patent Application WO/2014/073031

A1

A motor control device and a motor control method, whereby: in a measurement mode in which the variation waveform of a d axis current value for a permanent magnet (PM) motor is controlled in a rectangular wave shape, while the PM motor is rotating, and two current states are generated sequentially, a parameter calculation unit (127A) obtains the rotation speed of the PM motor calculated by a rotation speed calculation unit (126), on the basis of detection results from a rotation position detector (330). Furthermore, in said measurement mode, the parameter calculation unit (127A) obtains the d axis current value and a q axis current value obtained as a result of coordinate conversion of the detection results from the current detector (320) by a coordinate conversion unit (125). The parameter calculation unit (127A) also obtains a d axis control voltage value and a q axis control voltage value output from PI arithmetic calculation units (123q, 123d). The parameter calculation unit (127A) then calculates the circuit parameters for the PM motor (310), on the basis of these obtained results. As a result, the circuit parameters for the PM motor are precisely and readily measured.
