| Abstract |
This paper proposes initial rotor position estimation technique in three-phase permanent magnet synchronous motors (PMSMs) based on the magnetic saturation and saliency. Proposal technique extracts phase current dynamics caused by magnetic saturation and saliency respectively and simultaneously. Furthermore, this method has robustness against rotor position dependencies of d- and q-axis inductance. Therefore, this technique estimates initial rotor position accurately and shortly. |
