Abstract :
In this paper, a new PM brushless hybrid machine is proposed and implemented for wind power generation. The key is to incorporate a small DC field winding and an extra air bridge so that the airgap flux can be effectively strengthened or weakened to online keep the output voltage constant throughout the whole wind speed range. Based on its magnetic circuit, it can be derived that a small change in DC field excitation can induce a large change in airgap flux.
