Equally-divided combined amorphous stator core and manufacturing method thereof

Abstract

The invention discloses an equally-divided combined amorphous stator core and a manufacturing method. The invention discloses an equally-divided combined stator core. The amorphous alloy transformer comprises a plurality of amorphous iron core modules and silicon steel iron core modules which are arranged at intervals, wherein the two ends of the amorphous iron core are both silicon steel iron core modules; and each amorphous iron core module is formed by laminating a plurality of layers of annular amorphous iron core pieces; each amorphous iron core piece is equally divided into N amorphous iron core bodies; the N amorphous iron core bodies are connected with one another to form the annular amorphous iron core pieces; and joints of the adjacent layers of amorphous iron core pieces are laminated in a staggered manner. According to the invention, the mode of equally dividing the whole-circle amorphous and nanocrystalline stator iron cores and then combining the stator iron cores is adopted; the utilization rate of amorphous and nanocrystalline materials is greatly improved through pattern typesetting and cutting; and the material consumption of unit stator iron cores is reduced; considering the strength problem of the combined full-circle iron core, the technical scheme adopts the technical scheme that adjacent layers of joints are stacked in a staggered manner during axial lamination, and a plurality of layers of full-circle silicon steel chips are added after the amorphous stator iron core is stacked for a certain thickness, so that the overall strength of the iron core isenhanced, and the performance stability of the iron core is guaranteed.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an equal-section combined amorphous stator core and a manufacturing method. Background technique [0002] The amorphous stator core is the core component of the amorphous motor. At present, the amorphous stator core is mostly a circular structure, and the entire circle is indivisible, and the required number of slots is evenly distributed on the entire circle. Due to the limitation of the width of the amorphous strip (≤213mm), the outer diameter of the iron core is generally not greater than 205mm, which cannot be used to make large-diameter amorphous motors, which also limits the application prospects of amorphous motors in high-power motors. The utilization rate of the amorphous material of the amorphous stator made of the entire circle of the amorphous material is only about 30%, which is too much waste, which is not conducive to the cost competition between the amorphous motor...
