The essential difference between an A.C. dynamo and a D.C. dynamo is that

A.C. has an electromagnet but D.C. has a permanent magnet

A.C. has slip rings but D.C. has a commutator

A.C. will generate a higher voltage

A.C. has a coil wound on soft iron but the coil in D.C. is wound on copper

A.C. has slip rings but D.C. has a commutator

-The a.c dynamo has step rings because it changes polarity in every half cycle.
