Investigation of field regulation performance of a new hybrid excitation synchronous machine with dual-direction magnetic shunt rotor

This paper presents a new topology of hybrid excitation synchronous machine (HESM) with dual-direction magnetic shunt rotor. Firstly, the configuration characteristic, basic operation principle, and equivalent magnetic circuit are introduced. Then, 3D-FEA model of the proposed HESM are established. 3D-FEA results demonstrate that the proposed HESM has wide field regulation range and fault-tolerant ability. It is an efficient topology that significantly widens the application range of HESM with magnetic shunt rotor.
