摘要

A novel method for the estimation of the initial rotor position in a sensorless switched reluctance motor (SRM) was introduced per nonlinear simulation. The phase winding was energized by the narrow voltage pulse. The peak phase current was detected, and then the rotor position could be obtained through the analytical expression between the peak currents and the rotor position. The start-up of position sensorless SRM without reversing could be achieved. At the same time, the robustness of this method was studied and the principle for the selection of testing phase was obtained. Correlative experiments were implemented with a three-phase 6/4-pole SRM prototype. The experimental results verify the feasibility of this method and the principle of testing phase selection.
