AI Technical Summary
The existing motor signal magnetic rings cause internal cracks due to inconsistent shrinkage during injection molding, and are prone to break when pressed into the rotor shaft, resulting in problems of waste of materials and high costs.
The annular metal bracket and the magnetic ring body are integrally injection molded as inserts to form an injection molding fill layer to improve the connection strength and stability. By setting anti-rotation grooves and positioning flanges and stops on the magnetic ring body and the magnetic ring support, the axial positioning and anti-vibration impact performance are enhanced.
It reduces the safety hazards of internal cracks of magnetic ring caused by inconsistent shrinkage during injection molding, improves the reliability and service life of the product, reduces the amount of magnetic materials, and improves the anti-vibration impact performance.
