e offers a practical and beginner-friendly guide to understanding the principles of electric motors and related power devices. The course begins with an introduction to how motors work and common faults, including tips for maintenance and troubleshooting. Students then explore Variable Frequency Drives (VFDs) and IGBT inverters, learning how motor speed and torque are controlled efficiently in modern systems.
The course also covers single-phase induction and shaded pole motors, providing a clear explanation of their operation for beginners. Students are introduced to three-phase induction motors and universal motors, which are widely used in industrial and domestic applications. Additional lessons focus on power inverters and their working principles, explaining how AC and DC conversion enables energy-efficient operation in electrical devices.
A practical section demonstrates homemade transformers to illustrate voltage transformation principles, showing the relationship between turns, voltage, and current. By the end of the course, learners gain the knowledge to analyze motor operation, select appropriate motors and inverters, and apply troubleshooting strategies, providing a solid foundation for careers in electrical engineering, industrial automation, and renewable energy systems.
