| 简介 |
The present invention relates to a stator core assembly of a motor by forming a core unit around which a coil is wound with a divided structure using soft magnetic powder. A stator core unit of a motor according to an embodiment of the present invention comprises : a first yoke unit and a second yoke unit separated apart to face each other; and a winding unit whose both ends are connected with one side of the first yoke unit and one side of the second yoke unit facing each other, respectively to connect the first yoke unit and the second yoke unit and around which a coil is wound, wherein the first yoke unit, the second yoke unit and the winding unit are integrated by pressurizing and forming a mixture containing iron powder, rare-earth element powder and an insulation binder. The stator core unit of a motor according to an embodiment of the present invention can maintain a firm binding force between a plurality of divided core units without using laser welding and easily forming a complicated-shape structure, for example, a three-dimensional shape by sintering the plurality of divided core units using soft magnetic powder.COPYRIGHT KIPO 2016 |
