Abstract

See full text

A stator magnetic core and manufacturing process thereof and brushless motor comprising the stator magnetic core, wherein the stator magnetic core is made of iron-based amorphous material containing Co and V, and the composition of the iron-based amorphous material by weight percentage is: Co 0.8-1.4%, V 0.6-1.2%, B 2.7-3.3%, Si 6.5-8%, and Fe for the rest. A brushless DC motor, comprising a rotor spindle, a front end cover, a housing, a stator magnetic core and a rear end cover, wherein the stator magnetic core is assembled inside the housing, a stator coil is disposed inside the stator magnetic core, and the stator magnetic core and the stator core don't contact each other and an insulating layer is formed between them. The stator magnetic core in the present invention is made of iron-based amorphous material containing Co and V. Through addition of Co and V elements, the stator magnetic core refines crystalline grain and raises material toughness. It not only overcomes the previous problem of difficult machining and shaping but also raises the efficiency of the brushless DC motor containing this stator magnetic core. It is a breakthrough process.
