Relationship with Educational Objectives :
This class is equivalent to "(1) Cultivate human creative talent, rich in practical abilities", "(3) Acquire deep foundation knowledge of the major subject area".
Relationship with JABEE programs:
The main goal of learning/education in this class is "(A)", and "A-2".
Course outline:
The electrical apparatus is a widely used and indispensable device. The student will learn the principles, basic theory, and drive characteristics of the two types of AC motors (induction motor and synchronous motor) that are very important for understanding the basics of electrical apparatus.
Style:
Course method :
Classes are conducted using textbooks, and visually rich lectures using actual materials and projectors are also given as appropriate. Exercises are distributed as needed.
Grade evaluation method :
Exams (70%, An average score of 4 times exam) + Mini tests and Portfolio (30%).
Notice:
Precautions on the enrollment :
The students must take this class (no more than one-third of the required number of class hours may be missed) to complete the 3rd year course.
Course advice :
Always think by imagining the real thing, make calculations, and find the characteristics.
Foundational subjects:
Fundamentals of Integrated Science and Technology (1st year), Basic Electric (2nd), Electrical Apparatus Ⅰ (2nd)
Related subjects:
Power Electronics (5th yeaar), Design of Electrical and Electronic Machinery (4th), Electrical and Electronic Materials (5th), Engineering of Electric Power Generation (4th), Electric Power Transmission and Distribution( 4th), Regulations on Electrical Facilities (4th)
Attendance advice :
Make good preparations. Questions are welcome. This subject is useful for the Chief Electrical Engineer Examination (machinery, etc.). 20 minutes after the start of class will be considered late and 3 late arrivals will result in 1 absence.
