Abstract
Triggered by a position detection sensor detecting that a rotor is positioned at any one of K predetermined electrical angles, for example, 60°, 180°, and 300°, a voltage vector to be given to a motor is updated. When, for example, the rotation frequency is equal to or higher than a specified value, the predetermined electrical angles is changed into M, for example, into one angle of 60°.
