PM Wind Generator Topologies [PDF]

open access: yesIEEE Transactions on Industry Applications, 2005
The objective of this paper is to provide a comparison among permanent magnet (PM) wind generators of different topologies. Seven configurations are chosen for the comparison, consisting of both radial-flux and axial-flux machines. The comparison is done at seven power levels ranging from 1 to 200 kW.
