Title:
STATOR MAGNETIC CORE BRUSHLESS MOTOR APPARATUS, SYSTEM AND METHODS
Document Type and Number:
WIPO Patent Application WO/2017/017526
Kind Code:
A3
Abstract:
A stator magnetic core and manufacturing process thereof and a 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 an insulating layer is disposed between the stator magnetic core and the stator coil. The stator magnetic core and the stator coil don't contact each other. The stator magnetic core refines crystalline grain and raises material toughness by addition of Co and V elements. The problem of difficult machining and shaping is solved, and the efficiency of the brushless DC motor is improved.
