The paper presents an analysis and comparison of synchronous electrical machines with salient pole with field winding and those with peripheral winding, presenting important advantages. Chinese export restrictions already reduce the reliability of planning for investments in permanent magnet (PM) wind turbines. Today, the production of PMs consumes the largest proportion of rare earth elements, with 40% of the rare earth-based magnets used for generators and other electrical machines. The cost and availability of NdFeB magnets will likely determine the production rate of PM generators.
