Understanding DC Model and Machines — Lesson 8

This lesson covers the intricate details of the Direct Current (DC) model and its application in machines. It delves into the various types of windings a machine can have, such as series winding, compensating winding, and Interpol winding. The lesson then shifts focus to the study of simple machines. For instance, a DC motor, which is a simple machine, can have different types of windings for various functions, such as series winding for high torque.
