Course description and aims

This course "Design and Drawing of Electric Machine" enables to realize an economical and short-term manufacturing process of electrical machines satisfying the required performance in various applications and purposes. Then, it is required to know not only the knowledge already-studied in electrical engineering, such as electromagnetism and electrical machines, but also other knowledge in thermal and fluid dynamics, material mechanics, and so on. Therefore, at first, this course teaches the fundamental contents such as electric machine structures, manufacturing process, material selection, cooling technique, thermal estimation, magnetic characteristics, and so on. After that, it also provides the design procedures and exercises of single-phase transformers and synchronous generators as the examples of stationary and rotating machines. Finally, the fundamentals of technical drawings will be presented for the students to understood the design intent in design drawings and circuit diagrams.

Student learning outcomes

The aim of this course is to have the following abilities:
1) To understand and explain the basic structures, materials, and principles of electric machines from the design point of view.
2) To understand and explain not only electrical theories but also thermal conduction, mechanical stiffness, air flow, and so on regarding electric machine design.
3) To perform a practical design regarding single-phase transformers and synchronous machines.
4) To interpret design drawings and circuit diagrams with understanding the fundamentals in technical drawing.

Course taught by instructors with work experience

Applicable How instructors' work experience benefits the course
