Rotating Machines and Coil Dynamics — Lesson 4

This lesson covers the fundamental aspects of rotating machines, focusing on the role of coils and their dynamics. It explains the basic building blocks of any rotating machine, which include stator iron, rotor iron, slots, and windings. The lesson further elaborates on the concept of a single coil, which houses two coil sides and is placed in slots. It also discusses the induced voltage across the terminals of the coils when they rotate relative to a sinusoidally distributed magnetic field. The lesson provides a detailed explanation of the realms voltage in a single coil and how it is similar to that of a transformer. It also touches upon the concept of Fourier analysis and how it can be used to calculate the realms voltage of a periodic waveform.
