Assigned Department Objectives
Teaching Method
Outline:
The purpose is to understand the principle, structure, and various characteristics of transformers, which are AC power converters as well as static power converters. Basic characteristics of typical induction motors (mainly three-phase induction motors) and synchronous machines (mainly synchronous generators and synchronous motors) among AC rotating equipment based on the principle / structure and equivalent circuit of each rotating machine. Furthermore, the purpose is to understand how to operate these rotating machines.
Style:
In this class, we will deepen learning through group discussions. The goal is to acquire the ability to advance learning, discuss, and collaborate with others from different disciplines. Since this subject is a study unit, reports and online tests will be conducted as pre- and post-study.
[Class time 30 hours + self-study time 60 hours]
