Electrical Engineering is a technical basic course for electrical engineering and automation majors. Through the study of various types of motors in the process of generation, transmission and application of electric energy, we will be familiar with and master the working principles of these motors, understand the structure of the motor, master the analysis methods of the motor, and be familiar with the engineering applications of the motor. Based on the analytical thinking from actual motor devices to theoretical circuit models, and then to practical engineering applications, we will build a complete professional knowledge structure and follow-up professional courses for students, laying the necessary foundation for motor theory and engineering.
