The field system of DC generator has salient poles i.e. It consists of an even number of pole cores bolted to the yoke and field winding wound around the pole core. It produces the main magnetic flux in the generator. The magnetic field system of a DC generator is the stationary part of the machine. It provides a path for the magnetic flux produced by the field winding.

It supports the field pole core and acts as a protecting cover to the machine.

The outer frame of a DC generator is a hollow cylinder made up of cast steel or rolled steel is known as yoke. Here is the schematic diagram of a DC GeneratorĪ DC generator consists of six main parts, which are as follows Yoke The armature winding of DC Generator is placed on the rotor whereas the field winding is placed on the stator. The EMF induced in the armature winding of a DC generator is alternating one and is converted into direct voltage using a commutator mounted on the shaft of the generator. A DC generator has a field winding and an armature winding.

when the magnetic flux linking a conductor changes, an EMF is induced in the conductor. A DC generator is an electromechanical energy conversion device that converts mechanical power into DC electrical power through the process of electromagnetic induction.Ī DC generator operates on the principle of electromagnetic induction i.e.
