DC Generator Converted to Alternator

AI Thread 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 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
