《电力拖动控制线路》教学探索（The research on Teaching of electric drive control circuit） How to improve the teaching method of electric traction control circuit Abstract: Based on the requirement of students vocational skills training, combined with the actual basis of students, analysis of the existing general machinery, CNC electric drive control circuit in the textbook system problems, put forward to adjust teaching to improve teaching methods, teaching goal setting and teaching plan reasonable, appropriate to increase the new technology, new equipment content. Effectively improve the teaching effect of electric traction control circuit. Key words: control line; training; improvement Electric drive control circuit called control line in electric drive and skills training, the textbook has multiple versions, and repeated amendments, but the main teaching content system is basically the same, the commonly used low-voltage electrical appliances, motor control circuit, commonly used in the production of basic mechanical electrical control circuit and motor speed control system etc. part of individual teaching materials according to the current situation need to enrich the PLC teaching content, in addition to the theoretical teaching but also supporting a skills training content. But in general, all the content of the material lag is still serious, part of the teaching material is revised at the end of last century, the knowledge system arrangement is not reasonable, lack of science and the lateral contact students, the lack of systematic training of students skills. Therefore, the teaching method of electric traction control circuit needs to be improved. To make students faster and easier, to learn this course more easily, after groping their years of teaching, learning and teaching time considering the foundation of vocational students, requirements of vocational students in the limited hours to fully grasp the contents of this book is very difficult, therefore, in formulating th
