Abstract

The design of a permanent magnet generator for a wind turbine is studied. The best generator is chosen from a range of designs based on minimizing material cost and energy loss. The main loss mechanisms in an air-cored machine are copper and eddy current losses. The energy lost for each design is evaluated in the steady-state and then in the time domain so as to better take into account the thermal behavior of the machines.
