The frequency of the induced EMF in a three-phase alternator is given by f = PN/120, where P is the number of poles and N is the speed in RPM.

In a star (Wye) connection, the line current equals the phase current (IL = Iph).

An AC generator converts mechanical energy into electrical energy in AC form.

In a delta connection, line voltage equals the phase voltage, and line current equals phase current.

The rotor in large alternators is excited by a DC source via slip rings and brushes, a setup with an exciter.

The rotor of an AC generator is typically stationary while the armature rotates.

AC generators rely on direct current to create alternating current without any rotating magnetic field.

In a three-phase system, the line voltage is higher than the phase voltage and depends on the interconnection (star or delta).

Delta interconnection has phase voltage equal to the line voltage (Vph = VL) and line current equal to √3 times the phase current.
