This paper presents a method of estimating pole position of interior permanent magnet synchronous motors, IPMSMs. The proposed method estimates the pole position at low speeds and standstill by measuring only the DC link current of the inverter. The pole position is estimated by using the saliency of the IPMSMs. In order to detect the saliency, the three phase triangular carrier waves are used. The DC link current is measured at tops and bottoms of the carrier waves. Experimentation is performed to confirm the validity of the proposed method.
