The invention relates to a large-capacity double-C-type stator double-disk type rotor transverse magnetic flux permanent magnet wind-driven generator. The large-capacity double-C-type stator double-disk type rotor transverse magnetic flux permanent magnet wind-driven generator is characterized by comprising a stator (D) and a rotor (Z), wherein the rotor (Z) is connected with the stator (D) through a bearing (8); the stator comprises a fixed shaft (D1), a non-magnetic-conductive material cylinder (D2), U-shaped stator iron cores and an armature winding (D4); the non-magnetic-conductive material cylinder (D2) is fixed on the fixed shaft (D1); two groups of U-shaped stator iron cores are arranged in the non-magnetic-conductive material cylinder (D2); the stator iron cores comprise a first group of stator iron cores (D31) and a second group of stator iron cores (D32); and the first group of stator iron cores (D31) and the second group of stator iron cores (D32) are arranged opposite to each other at the interval of one time of polar distance. The large-capacity double-C-type stator double-disk type rotor transverse magnetic flux permanent magnet wind-driven generator can effectively reduce magnetic resistance of a magnetic loop so as to increase utilization ratio of motor magnetic flux.
Description
technical field [0001] The invention relates to a transverse flux generator, in particular to a large-capacity external rotor three-sided stator transverse flux permanent magnet wind generator utilizing three-sided air gaps in the field of high performance and direct drive. Background technique [0002] The non-renewability of fossil energy and serious pollution to the environment threaten the sustainable development of human society.
