| Abstract: | As the executing section of numerically controlled machine tool, AC servo devices' performance will af-fect the quality of feeder of the machine considerably. This paper introduces a new way for pulse duration modulating and self-regulation, which includes how to convert sine-wave signals into modulating wave of pulse duration and change to drive AC servomotor and madeuse of closed loop system to regulate the voltage outputting to AC seryomotor automatically to get steady rotate speed and higher machining precision. |
