"Electrical Machinery" is a professional basic course of power technology speciality. Taking specific electrical machine as the research object, this course systematically expounds the structure, working principle, electromagnetic relationship and operating characteristics of transformers, synchronous generators and asynchronous motors. The online course presents the whole course framework with continuous and granular knowledge points, integrates the requirements of professional post groups corresponding to power technology specialty for knowledge and skills into the course knowledge points, and fully displays the structure, working principle, electromagnetic relationship and other contents of the electric machine in front of learners by using various materials such as micro video, three-dimensional animation, courseware and pictures, And strengthens the necessary theoretical basis through online testing. At the same time, the typical cases in the practice of power production are used to cultivate learners' basic skills to analyze and solve motor related problems, and improve their professional technology application ability and innovation ability.
