Thermal Design of Electrical Machines

This course covers the comprehensive understanding of thermal design in electrical machines. It starts with the significance of thermal design, explaining how energy conversion in motors and generators leads to losses that are dissipated as heat, affecting the machine's output. The course then delves into the analogy between electrical and thermal domains using energy conservation principles. It further explores the principles of heat transfer methods in electrical machines, focusing on conduction, convection, and radiation. The course also discusses the various types of cooling methods used for electrical machines, including natural and forced cooling methods. It concludes with the fundamental aspects of thermal equivalent circuits in electrical machines, discussing related losses, thermal nodes, and how to analyze and design an appropriate thermal circuit.
