Why Doesn't a Synchronous Machine Induce EMF in DC Field Wires?

AI Thread Summary
A synchronous machine does not induce EMF in DC field wires because the relative motion between the rotating field and the magnetic field is not sufficient to generate an induced voltage. The current path through the windings creates a rotating magnetic field, but this does not lead to EMF in the DC field due to the nature of synchronous operation. The discussion highlights the importance of understanding the principles of electromagnetic induction and the role of amortisseur windings in this context. Questions raised focus on the misconceptions about EMF induction in synchronous machines. Clarifying these concepts is essential for a deeper understanding of synchronous machine operation.

conflict: why synchronous machine doesn't produce induced EMF in the DC field wires

Isn't it current path through winding which produce magnetic field (rotating) the must produce EMF in the dc winding of field (same theory of induction)

but why isn't true in synchronous

Two questions:

1. What makes you think it doesn't?
2. What is releative motion between rotating field wires and the magnetic field in which they rotate?

Read up on "amortisseur windings".

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...
