Abstract
The rotor position value is the most important parameter in synchronous machines. In this paper, a MATLAB model of high-resolution rotor position determination at zero speed, without any position sensor, is presented for a non-saturated permanent magnet motor. The motor current and voltage responses for two short pulses were employed to form address lines for memory cells whose contents represent the exact rotor position. The proposed model presents rotor position at 1o resolution and works with salient rotor poles. It could be modified to obtain the results for non-salient poles. The model needs only two current sensors and does not require any special technique for magnet polarity detection. This method was tested successfully for a two-poles machine and it could be applicable to any number of poles.
