Abstract:
1. A motor control device, wherein, let an axis parallel to a magnetic flux produced by a permanent magnet provided on a rotor of a motor be called a d-axis, let an axis leading the d-axis by an electrical angle of 90 degrees be called a q-axis, and let control axes corresponding to the d-axis and the q-axis be called a γ-axis and a δ-axis, respectively, then, the motor control device performs vector control of the motor with the γ-axis and the δ-axis made different from the d-axis and the q-axis, respectively, and with a motor current passing through the motor broken down into a -γ-axis current on the γ-axis and a δ-axis current on the δ-axis, wherein the motor control device comprises:
