DC Generator Converted to Alternator

Click For Summary
SUMMARY

A DC generator can be converted into an alternator by replacing the split ring commutator with a slip ring commutator. This modification allows the induced EMF in the rotor to be utilized as alternating current. To achieve single-phase output, sliding rings must be installed, and proper configuration of the coils in series and parallel is essential for the desired voltage and current. For a three-phase system, additional modifications to the windings and the installation of three or four rings are necessary.

PREREQUISITES
  • Understanding of commutators and slip rings
  • Basic knowledge of electromagnetic induction
  • Familiarity with electrical circuit configurations

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.
