Fundamentals of DC Machines and Operations

This course covers the fundamental concepts of Direct Current (DC) machines, their operations, and characteristics. It starts with the basics of how DC voltage is generated and the application of Faraday's law. The course then moves on to the complexities of converting AC voltage to DC, using the example of a conductor moving in a magnetic field to illustrate the process. It further explores the dynamics of a conductor at rest and how it experiences force when a current is applied. The course also delves into the operation of a simple linear DC machine, the concept of back EMF, and the effects of friction and load force. It concludes with an analysis of the steady state of DC machines, highlighting how to calculate the final current and speed.
