Abstract :
Effective cooling is of paramount importance for low speed permanent magnet (PM) machines due to their high power density and low speed. In this paper, a forced air cooling system for multibrid permanent magnet wind generator is presented, and the three dimensional temperature fields are calculated for this type of machine to verify the feasibility of the system. The steady state heat transfer mathematic models are established, and hypothetical conditions and loads are calculated. This thermal analysis technique is then validated after experimentation carried out on a 10kW prototype equipped with thermal sensors, and some valuable conclusions are obtained.
