Facing the background of more and more energy-saving in recent years, the market demand for high-efficiency motors is increasing, and the diversified demand for motor cores is also increasing.

Through the procurement of advanced equipment, the introduction of talents and the development of intelligent systems, our company provides customers with one-stop customized application solutions for motor stator and rotor cores to ensure that the solutions provided meet the accuracy and quality required by customers. At the same time, we will provide customers with the best solutions in the development of toolings and save costs for customers.

As for the tooling development scheme of motor core, whether it is stepper motor core, servo motor core, brushless motor core or new energy/automotive motor, our company adopts double-row stamping or more progressive die stamping technology, allowing the use of the same piece of material to stamp multiple rows of stators or multiple rows of rotors. Compared with the standard one-to-one method, the material efficiency is significantly improved. At the same time, according to the diversified needs of customers, we can also increase the large rotation process. That is to say, the product is rotated and laminated in the die, so that the parallelism and concentricity of the product are significantly improved. This tooling development solution saves resources and costs for the customer.

With regard to the tooling development scheme of the segmented stator core, the main technical difficulties lie in the key dimensions of inner and outer diameters and concentricity. At the same time, it is necessary to take into account the process gap between samples and mass production parts. When we cooperate with customers to develop such materials, we will recommend the development scheme of engineering die + progressive die. The standard of engineering die of segmented stator core designed by Yuma Precision is comparable to that of progressive die. This not only ensures the accuracy of key dimensions, but also minimizes the process loss related to the prototype, and the development results are closer to the design value.
