  journal={2012 IEEE Energy Conversion Congress and Exposition (ECCE)},
Recently a new type of wind generator concept known as a slip-synchronous permanent magnet generator was proposed. This is a gearless direct-drive generator which also connects directly to the grid, thus omitting the need for a power electronic converter. This generator consists of two machine units, a directly grid connected generator operating at synchronous speed and a directly turbine connected short-circuited generator unit. With the theory of designing the grid-connected permanent magnet… CONTINUE READING
