Will an alternator work at low RPM?

This is a function of the ratio between the crankshaft pulley and the alternator pulley. ... An alternator has a normal range of operation. Most alternators need to spin at about 2,400 rpm at idle, have their maximum output above 6,000 rpm, and should never exceed 18,000 rpm.

How do I reduce the RPM of my alternator?

The output of an alternator is controlled by regulating the field voltage. If the field is not at full voltage you can reduce the RPM by increasing the field and keep the output voltage.

What RPM do alternators run at?

Typically, alternators have their full output rated at 6000 RPM but can continue to spin up to 12,000 RPM or more without any additional increase in output. The speed of an alternator is different for different type of car.

Can you adjust alternator output?

Selecting different sized diodes can alter the output regulation of the alternator. A smaller diode will increase the charge voltage by more than a larger diode (due to the voltage drop varying with the diode current).

Will an alternator charge at idle?

Assuming the alternator, engine, belt, and battery are all in working order, then yes, a car battery will charge when idling. The only caveat is that it doesn't really “charge” that fast. This is solely due to the fact that the engine doesn't have a load on it when your car is simply idling.

What is the minimum RPM of a 12v car alternator?

Typically, the lowest speed at which a car alternator is able to generate 12VDC is about 1,800 RPM.

Can you make a wind turbine out of an alternator?

Windmills can provide you with electrical power for free – but to convert motion into current you'll need a generator. "A car alternator could be a handy solution if you're stuck, producing a steady 12 volts as its spindle is turned," says Dartnell.

What should a 12 volt alternator charge at?

A car alternator needs to be putting out at least 13-14 volts (ideally between 13.8 and 14.2 volts) to effectively charge a 12 volt car battery. If the alternator is putting out too much voltage (15+ volts), it is likely your battery acid will boil over out of the battery.

What happens when speed of alternator increases?

Now if the load increases to the alternator then the shaft of the alternator vibrate for a while and the speed of the shaft slightly decreases for very few amount of time but the shaft of the alternator will be dragged by the rotating magnetic poles ,provided by the three phase stator winding .

Will a bigger alternator hurt my car?

You can never have too much amperage when it comes to alternators; therefore, you never have to worry about choosing an alternator with too high of a rated output. ... So high-output alternators will not harm your components or charging system, no matter how high you go with the amps.

Can you run an alternator with an electric motor?

Yes you can run a Alternator with a electric motor. To figure the horse power it is 746 watts of power for 1 HP. that means you have to have 1.34 hp for each kw or kva.

How do you fix a low charging alternator?

Check the large power cable to the alternator and the fuse, usually, a large 40-60 amp fuse near the battery. Check the ground cable between the engine and the body. Check the serpentine belt and make sure the alternator is spinning with the engine. Check the small power supply wire and the charging light wire.

How does a voltage regulator controls alternator output?

The voltage regulator monitors the voltage coming out of the alternator and, when it reaches a threshold of about 14.5 volts, the regulator reduces the current in the rotor to weaken the magnetic field. When the voltage drops below this threshold, the current to the rotor is increased.

What is the exciter wire on an alternator?

The exciter wire is used to turn on the voltage regulator. This wire, when unplugged, should have approx. 12.5 volts with the key on. If it does not then the alternator will not work.
