摘要： 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.

摘要： In a method and module for controlling rotation of a motorized spindle driven by a driving unit, a sensing unit is adapted for sensing vibration of the spindle and generates a voltage signal corresponding to the vibration of the spindle. A processing unit is coupled to the sensing unit for receiving the voltage signal therefrom, and outputs a control signal corresponding to the voltage signal upon detecting that the voltage signal is greater than a reference voltage corresponding to a predetermined vibration level of the spindle, such that the driving unit adjusts a rotation speed of the spindle in response to the control signal from the processing unit.
