20150008779 | DISC-TYPE ELECTRIC MACHINE WITH AMORPHOUS IRON ALLOY AXIAL MAGNETIC CIRCUIT AS WELL AS ITS MANUFACTURING METHOD AND STATOR ASSEMBLY - A disc-type electric machine with amorphous iron alloy axial magnetic circuit, its stator iron core with an axial center through hole is processed into a cylinder made from amorphous iron alloy lamination, and its outer cylindrical surface is uniformly processed with a plurality of equi-spaced axial armature slots towards the center axial line. In the stator iron core embedded winding assemblies with the same number as the armature slots, each winding assembly comprises a winding wire frame matched with the armature slot, each stator winding arranged respectively in a slot of the winding wire frame and a magnetic conducting body arranged in a through hole of the winding wire frame. The said disc-type electric machine has short axial size, less moving components, small eddy current loss, excellent high-frequency characteristic, low temperature rising, high efficiency, high power density, high material utilization rate and high efficient energy-saving. | 01-08-2015 |
