Hence, the overall cost of alternator is reduced for generation of same amount of power.

Again, note that the transformer windings are not angled. Electrically, a Y is formed by the connections.

The lower connections of each winding are shorted together. These form the common point of the wye.

The opposite end of each winding is isolated. These ends form the arms 3 phase alternator the wye. The ac power on most ships is distributed by a three-phase, three-wire, volt system.

The single-phase transformers step the voltage down to volts. These transformers are connected delta-delta as in figure With a delta-delta configuration, the load may be a three-phase device connected to all phases; or, it may be 3 phase alternator single-phase device connected to only one phase.

The current that is fed through that coil is what determines how much voltage is produced by the alternator. 3 phase alternator you turn the key in the ignition, you are no doubt aware that there are two spots.

The first one connects the battery to the electrical system and may be labelled "accessories". The second spot is labelled "ignition" and this one connects the alternator field coils, and whatever engine controllers your more 3 phase alternator car may have.

The ignition light on your dashboard, traditionally, is in series with the field coil. It will be lit at this point because the coil is receiving max current and will go out when the engine is started and the alternator 3 phase alternator producing power and the field current is reduced.

The result of all this is that a small DC exciter current indirectly controls the output of the main alternator.

Small-scale examples are ubiquitous in engine-driven motive-power applications. This had a fixed "rotor" winding on the outer cover; the outer end of the iron core was a disc that closed the outer rotor pole. The rotor comprised two intermeshed six-pole "claws" welded to and spaced apart by a non-magnetic ring.

This was bolted directly to the end of the five-bearing crank via the hub of one pole. The other pole had an open end to receive the stator winding.

The outer cover also held the three-phase stator windings. The magnetic circuit had two auxiliary air gaps between the rotor and its stationary core.
