| Abstract: | To reduce the clutter interference of conventional motor control systems and overcome their complexity, the operation control chip which takes an industrial SCM as a core is designed. The zero-crossing trigger mode is adopted for SCR. The coordination and control of the major loop are completed by the software and hardware to dominate SCR to adjust the speed of a motor and reduce the clutter interference. The system is simple, and easy to test and maintain. |
