Motor and Electrical Control Technology is an important foundational course for majors such as mechatronics integration technology and electrical automation technology in higher vocational education. This course mainly includes three modules of motor, low-voltage electrical apparatus and motor control circuit, with a total of six items. The contents closely follow the knowledge points and skills required by the relevant professional standards of national electricians, and focus on practicality, applicability and progressiveness. The motor section focuses on introducing the structure, working principles, and applications of transformers, AC motors, DC motors, and special motors; The low-voltage electrical section focuses on introducing the structure, working principle, and selection principles of commonly used low-voltage electrical appliances; The motor control circuit section focuses on introducing the basic components of electrical control circuits.
