Pole unit and stator assembly for a wind turbine generator, and methods of manufacturing the same

摘要

There is described a pole unit for a stator assembly (100, 200, 300) of a wind turbine generator, the pole unit comprising (a) a laminated body structure comprising a base portion (110, 310), an intermediate portion (112, 312), and a top portion (114, 214, 314), and (b) a coil (116, 216) wound around the intermediate portion, wherein (c) the intermediate portion extends from at least a part of an upper surface of the base portion, and wherein (d) the top portion extends from the end of the intermediate portion that is opposite to the base portion and has an increasing cross-section in the direction away from the intermediate portion. There are further described a stator assembly comprising a plurality of pole units, a method of manufacturing a pole unit, and a method of assembling a stator assembly.
