Abstract

Doubly salient machine with a rectifier circuit constitutes a type of simple BLDC generators, which include doubly salient permanent magnet generator (DSPG), doubly salient electro-magnetic generator (DSEG) and doubly salient hybrid excitation generator (DSHEG). Magnetic field analysis of these generators is carried out based on finite element method (FEM). Hence, a comprehensive comparison of the static characteristics of these three kinds of generators is investigated. The output characteristics of these generators are compared by field-circuit coupled analysis. Results of comparing the three generators such as the voltage regulation, total mass of effective materials, the maximum power, power density and the efficiency are given.
