| Abstract: | The method of no touch and no step regulating speed and SCR substituted by FET to a low voltage motor based on proportional zero -voltage principle is presented in this paper. The problem about the life of touch points is solved by using SCR direct controlled with single-chip microc omputer. The rotary speed and position of motor are controlled by testing pulse signal of pulse wheel on the m otor axis using a counter port of the single -chip microcomputer. In testing and controlling, A/D and D/A conversi on is successfully avoided. |
