Abstract
A brushless motor control apparatus of a brushless motor which includes a permanent magnet type rotor and a stator, and which applies a harmonic voltage to a winding of the stator and measures the position of the rotor from the motor electrical current which is generated by the high frequency voltage, including an electrical current command control device which, in a magnetic pole discrimination procedure which discriminates the orientation of a magnetic pole of the rotor, varies a field electrical current command value based upon the position of the rotor.
