She has made significant contributions to the field of spindle motor technology, holding 2 patents that showcase her innovative spirit and technical expertise. Her work is instrumental in enhancing the performance and efficiency of spindle motors.
Latest Patents
One of her latest patents is a spindle motor with a seal structure. This invention comprises a stationary shaft and a rotor hub that is rotatably mounted by ball bearings to the stationary shaft. Annular sealing members are strategically disposed between the outer surface of the stationary shaft and the inner side of the rotor hub, positioned axially outwardly of the ball bearings. The sealing member is directly fitted onto the outer race of the corresponding ball bearing. The outer race of each ball bearing is high precision finished, ensuring that the sealing member is definitely coaxial with the stationary shaft, regardless of the finishing accuracy on the inner side of the rotor hub. This design minimizes the radial distance between the inner side of the sealing member and the outer surface of the stationary shaft, offering an excellent labyrinth effect.
