A General Analysis of Salient-Pole Characteristics of PMSM with Magnetic Cross-Coupling

Abstract

This paper presents a new general analysis about salient-pole characteristics of permanent-magnet synchronous motors (PMSMs) that have the magnetic cross-coupling. In the actual case with magnetic cross-coupling, salient-pole and N-pole phases are not the same, and there is phase error between them. The unique general solution of the phase error is presented.
