摘　　要：由于电工及拖动实验台将其组成的元器件封闭在内部,教学中配置教学用电动机。电工学、机电传动、可编程序控制器等实验课程中拖动类实验项目只能空载演示,这给学生掌握实验课程中的继电接触器控制动作原理、电动机拖动负载工作时电流与输出功率之间关系等相关知识带来一定难度。设计了面向生产现场的电机拖动实践教学平台,学生在教师的指导下完成课程设计。通过完成设计、制作电气控制装置、与电机拖动平台联机调试,既可以帮助学生解决实验教学过程中遇到的困惑,也能提高实践工作中的动手能力。Because the experimental teaching platform encloses the components inside and is configured with the teaching electric motor,the motor-driven experiment can only be demonstrated without load in experimental courses of electrotechnics,electromechanical transmission and programmable logic controller.The inadequacy confuses the students to understand the action principle of relay contactor control and the relationship between the current and output power when the motor drives the load.Through the teaching platform of electric motor drive oriented to the actual production site,students complete the course design of electrotechnics under the guidance of teachers.By completing the design and debug of electrical control devices with the motor driving platform,students can solve the puzzles encountered in the process of experimental teaching and improve their ability in practical work.
