  • Method for reducing the altitudinal errors and run-out of a spindle motor and a slim-type spindle motor
    Patent number: 7243360
    Abstract: A method for reducing the altitudinal errors and run-out of a spindle motor is disclosed. The method includes the following steps. First is to mount a material layer on the loading surface. Then, a surface treatment is applied to the material layer until the average run-out of the surface of the material layer is below 10?2 mm during the running of the spindle motor, and the distance between the surfaces of the material layer and one end of a shaft of the spindle motor achieves an expected value.
