Can we convert AC to DC in DC generator?

A split – ring commutator makes the current change direction every alternate half rotation whereas a slip ring commutator merely maintains a connection between the moving rotor and the stationary stator. Hence it converts an AC generator to DC generator.

How does the commutator change the AC voltage that is induced in the armature do a DC voltage output?

The commutator mechanically reverses the armature loop connections to the external circuit. This occurs at the same instant that the polarity of the voltage in the armature loop reverses. Through this process the commutator changes the generated ac voltage to a pulsating dc voltage as shown in the graph of figure 1-4.

Does commutator convert AC to DC or DC to AC?

Commutator converts the Alternating to direct current in a DC generator. The alternating current generated in the armature windings of the generator gets converted to direct current after it passes through the commutator and the brushes.

How can a commutator convert AC voltages on a machine’s armature to DC voltage at its terminal?

A commutator in a DC Machine has alternate bands of Copper and mica. Now when the armature starts to rotate by an external force (in DC Generator), the coils situated in the armature also rotate. The coils are shorted via brush segment with alternate change in influence of poles.

Which of the following is used to convert AC to DC in DC?

Commutator is used as mechanical rectifier in DC machines. It converts AC armature current in to DC current. Commutator is used to convert AC current into DC current.

Which part of a DC generator converts AC current into DC?

rectifier
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The reverse operation is performed by the inverter.

How does a commutator work in a dc motor?

The commutator on the DC generator converts the AC into pulsating DC. The commutator assures that the current from the generator always flows in one direction. The brushes ride on the commutator and make good electrical connections between the generator and the load.

Is commutator present in AC generator?

No commutator is present in AC Generator. To make the current flow in one direction only, DC Generator comprises the commutator.

Which part of DC machine converts AC into DC magnetic poles armature brushes commutator?

In the case of the DC generator, the commutator is used to convert generated AC in armature into DC.

How commutator convert AC to DC?

How Commutator Convert AC to DC? A commutator in a DC Machine has alternate bands of Copper and mica. Now when the armature starts to rotate by an external force (in DC Generator), the coils situated in the armature also rotate.

What is the commutation in a DC generator?

The commutation in DC machine or more specifically commutation in DC generator is the process in which generated alternating current in the armature winding of a dc machine is converted into direct current after going through the commutator and the stationary brushes.

How does a DC generator work with two brushes?

Imagine a DC generator with two coils on the rotor and two brushes that contact the commutator and carry the DC current out of the generator. The current in each brush always travels in the same direction. One brush flows in, the other brush flows out. How does the commutator convert AC to DC in a DC generator?

What is the difference between DC motor and DC generator?

the most interesting fact about DC machine is that the armature conductor always carries AC current while the brush carries the DC current. the commutator in the DC generator acts like an uncontrolled mechanical rectifier whereas in DC motor it acts like a mechanical inverter.
