This paper presents the electrical and magnetic characteristics of a permanent‐magnet induction generator (PMIG) under unbalanced grid voltages. The method of symmetrical components and two‐dimensional finite element analysis (2D‐FEA) are used to calculate these characteristics and the results are confirmed through experiments. Even if the voltage of the power grids is unbalanced, the PMIG can operate at high efficiency over a wide range of slip and the built‐in permanent‐magnet (PM) rotor is minimally affected by the negative‐sequence rotating field. © 2007 Wiley Periodicals, Inc.
