A DC Generator is an electrical device which converts mechanical energy into electrical energy. It mainly consists of three main parts, i.e. Magnetic field system, Armature and …
DC Motors How they work, in 4 parts — 12 November, 2001. History and background : Principles of operation: DC motor behavior: Parameterizing performance: Principles of operation. In any electric motor, operation is based on simple electromagnetism. A current-carrying conductor generates a magnetic field; when this is then placed in an external magnetic field, it will experience a force
In small generator, yoke are made of cast iron. Cast iron is cheaper in cost but heavier than steel. But for large construction of DC generator, where weight of the machine is concerned, lighter cast steel or rolled steel is preferable for constructing yoke of DC generator.
A.C generator works on former principle and D.C generator works on later principle. Usually copper wires coated with enamel is used for winding purpose. Aluminium is the next best material for winding of course the use of aluminium reduces the cost of the machine.
DC generators will act as DC motors if connected to a DC power source and not spun at a sufficient speed. This is a problem in DC power systems, as the generator will act as a load, drawing energy from the battery, when the engine or other “prime mover” device stops moving. This simple generator/battery circuit, for example, would not be practical for this reason:

A DC generator provides these three conditions to produce a DC voltage output. Theory of Operation A basic DC generator has four basic parts: (1) a magnetic field; (2) a single conductor, or loop;
identify, looking at the circuit diagram of a given generator, the types of the generator i.e., whether the generator is shunt, separately excited or compound generator. 3.

Parts of a DC Generator. Important parts of a DC generator are: Stator; It is the fixed and main part of the DC generator. The function of the stator is to supply the magnetic fields were the coils rotate. Stator consists of permanent magnets (two of them with opposite poles facing) which is placed to fit around the rotor. Rotor (Armature Core) Rotor is the next main part of the DC generator
Reduce the load within the specified generator rated output if the DC circuit protector is turned off. The fuel tank cap is provided with an air vent knob to stop fuel flow.
rainer designed to drive the dc motor so that various parameters of dc motor and dc generator can be found experimentally and determine the four transfer functions of armature controlled DC Motor, one transfer function of field controlled dc motor and one transfer function of dc generator.

In order for a DC generator to produce constant voltage, rather than brief pulses of voltage once every 1/2 revolution, there are multiple sets of coils making intermittent contact with the brushes.

Construction of DC Generator Yoke Pole Armature Brushes

FUNCTIONS OF ALTERNATOR COMPONENTS A typical rotating-field ac generator consists of an alternator and a smaller dc generator built into a single unit. The output of the alternator section supplies alternating voltage to the load. The only purpose for the dc generator is to supply the direct current required to maintain the alternator field. This dc generator is referred to as the exciter
