Introduction to Synchronous Machine. There are two main types of synchronous machine: cylindrical rotor and salient pole. In general, the former is confined to 2 and 4 pole turbine generators, while salient pole types are built with 4 poles upwards and include most classes of duty. On some alternating current (AC) machines, both EMF components are present because the coils are moving through a pulsating flux. It is convenient to use an alternative expression for induced EMF when relative motion is involved. In the normal machine, the conductors of the coils are constrained so that they move at right angles to the field.
