Course Objectives: Electrical machines, associated with the developments of power electronics, micro electronics, signal processing systems and control theory, are being used in most part of the daily life. As a result, earlier economic and technical limitations on control, performance and applications have been extended or removed. Therefore, it is important to know the performance of the electrical machines to define the overall system performance. The aim of this course is to provide basic knowledge of the electrical machines to the students of Electrical and Electronics Engineering, Energy Systems Engineering, and Mechatronic Engineering departments.
