Motor Integrated Training System Based On Modern Control Technology Research And Development

This subject designs an comprehensive electric motor controlling system which uses PLC technique, frequency controlling technique and traditional controlling technique of the relay. It can also realize online debugging combining with computer and programmble software STEP7-Micro/WIN V4.0.This system can simply use relay to control the motor's running. It can also use relay, PLC and variable frequency controlling technique comprehensively to control motor's running. Because relay is indispensable for mortor control, PLC and variable frequency controlling technique are based on the relay controlling technique. Speaking concretely, relay matches with motor can accomplish basic motor control and machine tool control. Relay and PLC match with motor can accomplish the improved controlling function. Frequency conversion matches with motor can accomplish speed-and-frequency adjusting function. Relay, PLC and frequency conversion match with motor can accomplish comprehensive motor controlling function.This paper firstly discusses the designing progress and the hardware's selection of the system. Equippments' safety, components' function, configuration and market demanding are all taken into the designing account. Secondly, it introduces the application of the STEP7-Micro/WIN V4.0 software, it's a Windows-based application software with great function for both user's program designing and real-time checking for the program's running state. Finally, this paper analyses some experimentation example in order to find the problems and make improvement.Now, more and more colleges pay attention to students' practical technical ability. This system will create a good condition to improve the student's practical technique so they can be more competent for society. The system can also offer training for those who have worked. So that, it has huge application value.
