There are two basic types of three-phase alternators:
The revolving- __________ -type rotates the three single-phase windings, located 120 mechanical degrees apart on the rotor assembly, around the inside of a fixed or stationary electromagnetic field.
The revolving- __________ -type rotates is constructed by placing the three sets of single-phase windings 120 mechanical degrees apart on a metal core around the inside of a metal housing that supports the core (the stator assembly).
An electromagnet placed in the centre of the windings is rotated around the inside of the stator assembly of the three sets of single-phase windings.
