Problems solved by technology

However, multiple sheets are formed by centralized punching, which is not conducive to the subsequent classification of the sheets that make up the fan-shaped tooth block, which in turn affects the forming efficiency of the rotor. In addition, the tooth block formed by stacking multiple sheets, The consistency of the product cannot be guaranteed, and thus the industrialized mass production cannot be carried out

Abstract

The invention provides a forming method for silicon steel blocks of a rotor of an axial switch reluctance motor. The forming method comprises the following steps of: (a) providing a silicon steel plate disc , wherein the silicon steel plate disc has an inner end part, an outer end part and a plurality of fixing holes penetrating through the inner end part and the outer end part, and the silicon steel block is formed between every two adjacent fixing holes; (b) providing a plurality of tooth bars, and sequentially inserting the tooth bars into the fixing holes one by one; (c) providing a shape fixing assembly, and fixing the shape fixing assembly on the inner end part and the outer end part; and (d) cutting along cutting positions defined between the silicon steel blocks and the fixing holes to obtain a plurality of silicon steel blocks for assembling the rotor. The silicon steel sheet disc is divided into the plurality of silicon steel blocks in the same shape by using the fixing holes, and the plurality of silicon steel blocks are separated through cutting and can be correspondingly assembled into the rotor, so that the forming is convenient and fast, the consistency of the product shape is guaranteed, and the industrial batch production is realized.

Description

technical field [0001] The invention relates to the field of motors, in particular to a method for forming a rotor silicon steel block of an axial switched reluctance motor. Background technique [0002] Axial switched reluctance motors are simple, energy-efficient electromagnetic devices. In particular, axial switched reluctance motors are widely used in electric vehicles, general industries, and home appliances due to their small axial size, high torque-to-inertia ratio, high power density, and high efficiency. [0003] Existing axial switched reluctance motors generally use silicon steel sheets as the lamination material of the stator and rotor. Taking the rotor as an example, silicon steel sheets are punched to form multiple sheets of different widths, and then the sheets are sequentially pressed according to the width. The larger method is stacked to form a plurality of fan-shaped tooth blocks of the same shape, and finally the multiple tooth blocks are arranged on the...
