引言《电力拖动》是我校机电专业的一门核心专业课程。主要介绍的是电动机的启动、制动、调速方法的基本方法、原理。近几年通过对我校机电、数控、模具等专业学生学习兴趣的调研发现,大多数学生不喜欢在教室上理论课,而喜欢在实训室上实践课。这是因为中职学生在初中的学习中基础不扎实,对抽象的理论知识难以理解,对直观具体的实践操作感兴趣,比较容易掌握。根据中职职业学校学生的认知特点,让学生先有感性认识,然后再进一步实践, Introduction “Electric Drive” is one of the core professional courses of Electrical and Mechanical Engineering in our university. The main introduction is the motor starting, braking, speed control method of the basic methods and principles. In recent years, through my research on the interest of students in electromechanical, numerical control, mold and other professional learning in our university, most students do not like the theory class in the classroom, but like to practice class in the training room. This is because secondary vocational students in junior high school learning is not solid foundation for the theoretical knowledge of abstract difficult to understand, intuitive and practical action is more interested in, easier to grasp. According to the cognitive characteristics of vocational school students, so that students have perceptual knowledge, and then further practice,
