  • Patent number: 8653765
    Abstract: In a method and module for controlling rotation of a motorized spindle driven by a driving unit, a sensing unit senses vibration of the spindle and generates a voltage signal corresponding to the vibration of the spindle. A processing unit receives the voltage signal from the sensing unit, generates an adjusting ratio equal to a reference voltage corresponding to a predetermined vibration level of the spindle by the voltage signal upon detecting that the voltage signal is greater than the reference voltage and is less than a predetermined threshold voltage that is greater than the reference voltage, and outputs a control signal corresponding to the adjusting ratio to the driving unit such that the driving unit reduces a rotation speed of the spindle by the adjusting ratio in response to the control signal from the processing unit.

  • Publication number: 20100249982
    Abstract: In a displacement compensation control method and module for an object mounted movably on a driving rod unit and movable between first and second positions relative to the driving rod unit during processing, a detecting unit determines a displacement amount of a free end of the driving rod unit from a reference position in an axial direction of the driving rod unit as a result of thermal deformation of the driving rod unit during high-speed rotation. A control unit controls the driving rod unit to rotate based on the displacement amount so that the object moves between first and second compensation positions relative to the driving rod unit. A distance between the first position and the first compensation position, and a distance between the second position and the second compensation position are equal to the displacement amount.
