A method for driving a servo-motor detects a power voltage of a servo-motor determine a detected value. Through numeric calculation, the detected value is used to control a voltage command to a power converter, where the power converter supplies the proper currents to the servo-motor. The method does not require the use of a feedback loop, and thus, requires fewer components than the traditional method that also requires the use of a current sensor and an A/D converter.
