Abstract :
In this paper, an estimation method of rotor position for 3-phase SRM based on the space vector of inductance at standstill and during rotating condition is described. The rotor position at standstill is obtained simply without magnetic characteristics of the motor and additional hardware. Assuming the inductance waveform to be sine wave, the rotor position at standstill is obtained by computing the angle of space vector of inductance. During rotation, the rotor position estimation is carried out by applying DC bus voltage to the idle phases over a short time. The validity of the proposed method is verified by experimental results.
