Abstract: PURPOSE: A method and an apparatus for estimating the initial rotor of a permanent magnet synchronous motor are provided to facilitate algorithm embodiment. CONSTITUTION: A vector control mode supports a SVPWM(Space Vector Power Width Modulation)(30). Current information is collected from four vectors among six vectors. The collected current information is compared. The position of a rotor is presumed based on comparison result. [Reference numerals] (40) Initial rotor position estimating apparatus
