Principles of DC Machines

Principles of DC Machines

DC Machines are the electro mechanical energy converters which work from a d.c source and generate mechanical power or convert mechanical power into a d.c. power. These machines can be broadly classified into two types, on the basis of their magnetic structure. They are, Homopolar machines Heteropolar machines Homopolar Machines :- Homopolar Generators – A homo-polar generator is a DC electrical generator comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. A potential difference is…
