Content

Motivation:

Education in Electric drives is essential in the formation of engineers as it equips them with a systematic approach to navigate the complexity and wide-ranging applications of drive systems. In an era where drive systems are becoming increasingly intricate, including motors, control mechanisms, and system integration, a structured understanding is crucial. This course provides students with the tools and knowledge to analyze, design, and implement drive systems effectively, fostering a systematic mindset applicable across various engineering disciplines.

By emphasizing a systematic approach, the course enables students to identify and address challenges, optimize system efficiency, and ensure reliable operation. Moreover, it prepares them to stay at the forefront of technological advancements in motor technology, power electronics, and control techniques. With this comprehensive understanding, students are well-equipped to make informed decisions, troubleshoot problems, and contribute to ongoing research and innovation in drive systems.
