Learn how a DC generator works, its principle, parts, diagram, and the differences from AC generators. Perfect for students and quick revision. A DC generator is an electrical machine that converts mechanical energy into direct current (DC) electricity using the principle of electromagnetic induction. It produces a unidirectional current through a commutator. This article outlines basic construction and working of a DC generator. Key learnings: DC Generator Types: DC generators are mainly divided into three types based on their field excitation methods: permanent magnet, separately excited, and self-excited. Self Excited Generator: A self-excited DC generator uses its own output to power its field coils, which can be arranged as series, shunt, or compound wound. Application Insight: Portable generators often use DC generator technology due to its reliability and efficiency in generating electricity. Generator ... Learn how a DC generator converts mechanical energy into direct current electricity using electromagnetic induction. Explore the main components, types, characteristics, advantages, disadvantages and applications of DC generators.
