As the heart part of the motor, the quality of the motor core directly affects the performance and efficiency of the motor. Most electrical steel sheets are assembled into cores by welding, bolt connection, self buckle or riveting. However, the welding fixation method will cause various problems such as short circuit at the edge of the core, decline in insulation, and deterioration of magnetic properties due to thermal deformation. Whether it is welding, bolt connection, self fastening or riveting, the iron core is fixed locally, the connection force is not high, and it is difficult to meet the high requirements for fastening strength. In addition, the welding and riveting methods are not applicable to many micro motors.

Hongda self-adhesive iron core adopts the method of bonding the motor punching pieces together to form the iron core as a fixing method. The motor punching pieces are self-adhesive fixed iron core laminations, which are fixed on the whole surface of the iron core, and the fixing strength is greatly improved. At present, it is widely used in the fields of marine exploration, electric vehicles, aviation, rail transit and military aerospace.
