Abstract

See full text

The method for detecting an initial position of a magnetic pole of a rotor included in a permanent magnet synchronous motor according to an embodiment of the present disclosure includes generating three-phase voltage vectors to be applied onto a u-phase, a v-phase, and a w-phase of a stator winding, applying the three-phase voltage vectors on the u-phase, the v-phase, and the w-phase of a stator winding, respectively, calculating a current difference value of the u-phase, a current difference value of the v-phase, and a current difference value of the w-phase using currents of the stator winding flowing in a magnetizing direction and in a un-magnetizing direction by applying the three-phase voltage vectors, and determining the initial position of the magnetic pole of the rotor using the current difference value of the u-phase, the current difference value of the v-phase, and the current difference value of the w-phase.
