DC Generator Converted to Alternator

Click For Summary
A DC generator can be converted into an alternator by replacing the split ring commutator with a slip ring commutator. This change allows the induced EMF in the rotor to be utilized as alternating current instead of direct current. Proper configuration of the coils in series and parallel is necessary to achieve the desired voltage and current output. For a three-phase system, modifications to the windings and potentially additional rings are required. This conversion process enables the generator to produce alternative single-phase or three-phase current.

Yes. Just change the split ring commutator to a slip ring commutator.
 
Actually the EMF induced in rotor it is an alternative EMF. The commutator acts like a rectifier and the brushes collect a rectified d.c. current.

As Aceix said, if instead of commutator you'll fit sliding rings you could get alternative-single phase current. However, you have to check how to connect the coils in series and parallel in order to get the required voltage and current.

In order to get three-phase system -except three or four rings-you will need to modify the windings also.
 

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
