Study Notes

DC Generator Function

  • The DC generator converts mechanical energy into direct current (DC) electrical energy.

Commutator Role

  • The commutator serves as a mechanical switch that periodically reverses the current direction in the armature windings, allowing the DC generator to produce a unidirectional output.

Field Winding Open-Circuit

  • If the field winding in a DC generator is open-circuited, the magnetic field collapses, and the generator stops producing voltage.

Test your knowledge about the function and components of a DC generator with these questions. Learn about the role of the commutator and the consequences of an open-circuited field winding in a DC generator.
