Analysis of a new dual-stator doubly salient brushless DC generator

This paper presents a new dual-stator doubly salient brushless DC generator (DSBLDCG). The key of the proposed generator is to reduce the voltage and torque ripples. Finite element analysis (FEA) of the generator is carried out to investigate the magnetic field distribution at different rotor positions. Furthermore, flux-linkage and inductance characteristics are also given. The simulation of the generator with three-phase half-wave common anode rectifier circuit is well performed. The results from the finite element analysis verify the theory analysis and the rationality of the generator. It shows that the structure of the dual-stator can decrease the voltage ripple effectively, especially under heavy load conditions.
