Introduction to Dynamo-Electric Machinery and DC Generators
- Dynamo-electric machinery converts mechanical motion into electric currents and vice versa through the principle of electro-magnetic induction.
- The term "dynamo-electric machine" was first used by Dr. Werner Siemens in 1867 to describe a machine for generating electric currents using mechanical power.
- There are three types of dynamo-electric machines: self-excited dynamos, shunt dynamos, and separately-excited dynamos.
- Separately-excited dynamos have their field winding excited from an external source of DC supply.
- The magnitude of the generated voltage of separately-excited generators is regulated by changing the field current or the speed of armature rotation.
- The distinction between magnetoelectric machines and dynamo-electric machines fails when examined carefully, as both use magnets to provide a field of magnetic force.
- Graphical methods, such as the "characteristic" curve, can be used to represent the action of a dynamo.
- A generator is an electromechanical energy conversion device that converts mechanical energy into electrical energy.
- A DC generator converts rotational mechanical energy into electrical energy in the form of DC.
- There are different types of DC generators, including separately-excited DC generators.
- DC generator voltage regulation can be achieved by changing the field current or the speed of armature rotation.
- DC generators are commonly used in various applications, including in electric vehicles, backup power systems, and in small-scale power generation.
