deuce generator vs alternator

[kipman]

What advantage does the generators have over the a alternator and is it worth the swap?

 

[Blood_of_Tyrants]

A generator uses permanent magnets for the magnetic field and an alternator uses electromagnets to generate the eledtric field. The electromagnets can be controlled much more precisely to give the current required. alternators can be made smaller, lighter, and cheaper. NOBODY puts a generator on modern vehicles.

A gasoline vehicle with a generator can have a completely dead battery can be push started as the wire wound rotor will generate an electrical current as the wires pass through the permanent magnetic field. But an alternator requires SOME electrical energy to generate the magnetic field, to allow it to generate power therefore you cannot push start a vehicle if the battery gets too low.

An old points and condenser type distributor on a car would allow it to run with a bad alternator until the battery was almost completely dead. But the newer cars with all the electronic controls will not run if the voltage drops below about 10.5 volts.

also the alternators available for the duece put out more amps than the generator.

Generally 25 amps for the generator with an external regulator and 60 amps for the standard alternator with an internal regulator.

I wouldn't go from a alternator to a generator.

I have the kits to convert from the 25 amp generator to the 60 amp alternator, genuine gummint, for $25....no alternator included, of course... but all the wiring and adaptors for sure...brand new sealed packages... 00-000-0088

Generators, as used in the general automotive field, do not have permanent magnets for the field. While the field does have some residual magnetism, it is actually an electromagnet. Without it, you would not have any control over the generator's output voltage.

There are several benefits of alternators over generators. The most important is that an alternator's power is generated in the stator (field) and rectified with diodes. Only a small amount of current passes through an alternator's brushes/ slip rings. The generator's power is created in the armature and rectified with the commutator/ brushes. All of the power has to pass through the commutator and brushes. This places a practical power limit on a given generator size. An alternator can also be spun much faster due to it's construction. This enables it to be overdriven compared to a generator giving you more output at engine idle speed.
