Dynamo

A dynamo is an electrical generator that creates direct current using a commutator, and uses self-powering electromagnets for the stator field rather than permanent magnets. Dynamos are self-starting by using residual magnetic field left in the iron cores of the electromagnets (i.e. field coils). If a dynamo were never run before, it was usual to use a…
