This course covers the comprehensive understanding of Direct Current (DC) machines and their models. It begins with the derivation of machine equations, focusing on a four-coil primitive machine. The course then explores the system description in the optional impedance form, explaining the concepts of self-impedance, mutual impedance, and speed EMF terms. It also provides a detailed description of a DC machine, including the field winding, armature, and the role of brushes. The course further delves into the concept of small signal models, their derivation from large signal models, and their application in control system applications. It also illustrates how changes in armature voltage can affect the machine's speed. Lastly, the course discusses the small signal behavior of DC machines, using a 5HP DC machine as an illustrative example.
