The motor core is a component that corresponds to the iron core part of the rotor (rotating part) and stator (stationary part) that make up a motor. For example, more than 50 motors are used in a single automobile. At Hirai Precision Industry, we can offer manufacturing of motor cores through etching and machining processes. The etching process is characterized by the absence of burrs in the thickness direction of the processed motor core itself. 【About the processing methods】 ■ Etching process - The absence of burrs in the thickness direction of the processed motor core itself is a feature. - Electrical steel sheets have an insulating film on both sides, and processing can be done while leaving this insulating film intact on both sides. ■ Machining process - Options for laser processing and wire processing are available. *For more details, please refer to the PDF materials or feel free to contact us.
