Purpose of class
Acquire practical fundamental design methods for electrical machines—such as single-phase transformers and synchronous machines—by learning their structures, materials, and underlying theories that form the basis of electrical machine design.
Course description
In electrical machine design, in addition to electrical knowledge such as electromagnetics and electric circuits, it is necessary to have knowledge outside the electrical field, including heat transfer, fluid mechanics, and strength of materials, as well as practical knowledge related to machine fabrication. Therefore, this course begins with the fundamentals of electrical machines, including their structure, fabrication methods, material selection, cooling methods, temperature calculations, and magnetic circuit calculations. Subsequently, students will learn the practical design basics of stationary and rotating machines, using single-phase transformers and synchronous generators as examples.

[Prerequisites] Completion of Electric Circuits I and II.
[Related Courses] Electric Circuits I and II, Electromagnetics I, Power Electronics.
Goals and objectives
  1. Students will be able to explain the basic structure, materials used, and operating principles of transformers and rotating machines.
  2. Students will be able to explain the fundamental aspects of electrical machine design, such as load and flux distribution.
  3. Students will be able to perform practical basic design of single-phase transformers.
  4. Students will be able to perform practical basic design of synchronous machines.

Evaluation method and criteria
Evaluation is based on the average score of two reports (each scored out of 100 points), with 60 points or higher considered a passing grade. Reports are assessed on the assumption that the entire design process has been carried out and that all weekly assignments have been completed.
Note: Points may be deducted if reports are not prepared concisely and carefully.
Evaluation methods and criteria may be partially revised.
