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

    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".
