In some applications, there are high requirements on the structure and quality of the motor. The motor core is an important part of the motor and an important part for transmitting, transporting and converting energy.
现有技术中，电机铁芯的制作方法有1.电机铁芯单片冲压叠铆，2.电机铁芯拼片拼块叠铆，3.电机铁芯铰链式拼块整合方式，4.电机铁芯卷绕式工艺等方式。In the prior art, the manufacturing methods of the motor core include 1. single-piece punching and riveting of the motor core, 2. stacking and riveting of the motor core, 3. hinged block integration of the motor core, 4. motor core Iron core winding process, etc.

2、电机的综合性能无法有效的提升。电机铁芯槽口大小的选择为在满足嵌线和加工工艺的前提下，比绕组线径稍大，尽量取一个较小的值。而槽口的大小对电机的性能有着决定性的影响，现有工艺影响了电机的综合效率。2. The comprehensive performance of the motor cannot be effectively improved. The size of the notch of the motor core is selected to be slightly larger than the diameter of the winding wire under the premise of satisfying the embedding and processing technology, and try to take a smaller value. The size of the notch has a decisive impact on the performance of the motor, and the existing technology affects the overall efficiency of the motor.
3、卷绕钢带无法实现对插，造成大量的废料。传统的电机铁芯，齿头是按技术参数要求一次冲压成型，往往由于结构设计问题，齿头宽度大于嵌线槽宽度，其结构如图1、图2所示，无法形成铁芯的料带对插，这样就导致原料的利用率较低，产生的废料较多，成本随之上升。3. The coiled steel strip cannot be inserted into each other, resulting in a large amount of waste. In the traditional motor iron core, the tooth head is stamped and formed in one time according to the technical parameters. Often due to structural design problems, the width of the tooth head is larger than the width of the embedding slot. Its structure is shown in Figure 1 and Figure 2. Inserting each other, this will lead to a lower utilization rate of raw materials, more waste generated, and the cost will increase accordingly.
