Regulation of an alternator is varying or adjusting the d.c. current flow (excitation current) in the revolving field coil to control the output voltage. When an alternator is subject to varying load conditions, and therefore changing load resistance at the output, the output voltage will vary in response. When output voltage is reduced in response to increased load (reduced output resistance), the "voltage regulator" will respond by increasing the excitation current to increase the voltage output. If load is reduced, the generator will momentarily become over-excited and the ouput voltage will increase. The voltage regulator responds by decreasing excitation current, returning the generator output voltage to its nominal level.
What else can I help you with?
Is voltage regulation important in an alternator?
yes
What is Regulation of alternator by synchronous impedance method?
It is conducting OC and SC tests on the given three phase alternator and determining the regulation by synchronous impedance method.
What is alternator voltage regulation?
change in voltage from no load to full load
Why voltage regulation is required in alternator?
To regulate the voltage flow going to the battery.
What happened when you decrese the voltage regulation of alternaTOR?
If you were to be able to decrease the amount of regulation in an alternator, the voltage outputs would become unstable and probably ruin the battery or any devices that run directly from the alternator source. I am not saying that it will happen but it certainly would effect the systems in some way.
Where is the voltage regulation system on vauxhall tigra?
Since shortly after the invention of the Alternator, most vehicle manufacturers have implemented a regulator INSIDE the alternator. Solid state regulators are small and relatively inexpensive and it's generally recommended that if the alternator fails, just replace brushes, bearings, regulator and diodes... which is pretty much what you get with a QUALITY rebuilt alternator.
Why is voltage regulation important in alternator?
because the voltage should be constant as the full transmission grid need ame voltage for synchronization of alternatos of grid
Where does the Excess current produced in a alternator charging system goes?
Actually it is bled off to ground but because of a very well designed regulation system in most alternators, there really isn't anything excess. When it is not being drawn from the alternator, it goes to the battery.
What is meant by regulation?
The general noun, regulation, means control by rules. e.g. "Regulation of the pharmaceutical industry ended the craze for using radioactive substances as medicine." However, "a regulation" is a particular rule. In some places it refers to rules created by the civil service which have the force of law although they are not statutes. "A health department regulation forbids the holding of pot luck suppers in public places."
How are the wiring for a 2005 ford focus alternator connected?
The wiring for a 2005 Ford Focus alternator typically involves three main connections: the battery positive terminal, which connects to the alternator's output terminal; the field wire, which connects to the alternator's exciter terminal for voltage regulation; and the ground, which is usually connected to the alternator's casing or mounting bracket. Ensure all connections are secure and free from corrosion for optimal performance. Always refer to the vehicle’s service manual for specific wiring diagrams and procedures.
What controls the voltage regulation for the 1991 ford escape's alternator?
the voltage regulator can be found on the back of alternator,probably the brushes worn if giving you troble But hopefully you wont have to change it, because it involves removing an axle, jacking up the engine after disconnecting a motor mount, a real difficult knuckle-buster job
Can you suggest a circuit diagram for voltage regulation of 3 phase permanent magnet alternator for a constant output 230volts?
The normal method for controlling output of an alternator is to vary the field current. In a PM alternator, there would be no field windings to control. The only way I could think of would be to vary the speed of rotation. This might work if the output was rectified (DC), but would be a problem if the output is AC, since the frequency would also change. I have not seen a PM alternator per se. Unusual.
