This paper presents an estimation method of rotor position at low speeds for permanent magnet synchronous motors (PMSM)
using a high frequency (HF) square wave voltage injection technique at a low switching frequency. This method utilized variations in

-axis current
along with a straightforward design principle provided for the zero and pole points of the Luenberger state observer. The experimental results show that the proposed sensorless control algorithm is effective in accurately tracking actual values in the rotor speed and position estimation at low switching frequency.
