Quick Answer: What Is The Most Powerful Alternator?

How can I make my alternator more powerful?

You can achieve a higher peak amperage by putting fewer turns of heavier wire on the alternator stator windings.

That reduces the winding impedance and lets more current flow, provided you have enough changing magnetic flux to excite the windings..

How big of an alternator do I need for 5000 watts?

It’s going to consume 7142 watts to create that 5000 watts. 7142 / 14.4 = 496a. You will need 532 amps of alt to sustain this amp constantly while running the car and a few accessories.

Can high rpm damage alternator?

TOO HIGH OF RPM WILL DAMAGE ANYTHING. INCLUDING ALTERNATORS. YOU IMPORTANTLY MUST BE AWARE THAT IF THE ALTERNATOR IS BELT DRIVEN, THE DIFFERENCE IN SIZE OF THE TWO BELT PULLEYS MIGHT HAVE THE ALTERNATOR TURNING FASTER THAN THE ENGINE RPM, MAYBE MANY TIMES FASTER. TOO HIGH OF RPM WILL DAMAGE ANYTHING.

Does revving engine charge battery faster?

Revving the engine will charge the battery faster because the alternator increases this amperage. When you rev the engine, the alternator begins to run faster, which helps charge the battery.

What is the highest output alternator?

The highest 12 volt produced by Prestolite Leece-Neville is the J-180 mount 4890JB and Pad Mount 4962PA both of which put out 320 amps. When it comes to 24 volt alternators there is one manufacturers that really stands out – C.E. Niehoff has their 500 Amp C-803D.

At what RPM does a alternator charge?

Alternator may not generate sufficient charging voltage until alternator speed is greater than about 2000 RPM. 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.

Can subs ruin your alternator?

Subs (being inductive) cause a lagging power factor causing the amp and battery to draw more power than is required. A cap is dangerous as it gets charged up but as I said a cap is not a replacement for a battery. it smothes out voltage spikes, making it easyer on your battery and alternator.

How many amps does an alternator put out at idle?

50 ampsAt idle speeds of about 650 RPM it can only produce 50 amps or so. This is why when you have a loose alternator belt or a defective belt tensioner, you only hear the squeal when you hit the gas initially after you start the engine, not with the engine idling.

How do I choose the right alternator?

How to Choose an AlternatorMake a list of your electrical components.Determine amp draw on each and total.Select an alternator with more amps than estimated to ensure long life of the alternator.See our website for additional tips.Call our Tech Support Line for selection assistance…

Is a higher amp alternator better?

A higher amperage alternator will not pose any problems to the vehicle’s electrical system. Amperage will flow to only those components that can use the energy and supply as much amperage as the component can consume.

What is the big 3 upgrade?

What is the Big 3 Upgrade? Most factory charging systems can only take 500-1000 watts of additional power without seeing much fluctuation in voltage. The Big 3 gains it’s name from the 3 main power wires that connect the alternator, the engine block and the chassis, to the battery.

What are the symptoms of a bad alternator?

6 Symptoms of a Failing AlternatorThe indicator light. … Headlights are dim or flickering. … Other electrical failures. … Strange noises. … Car stalls or has difficulty starting. … Battery dies.

Can a car alternator power a house?

First of all you need a steady source of rotational power in your home to turn the generator. If you don’t have that you are no-go. An alternator will put out perhaps 20–50 amps at 14 volts… that’s about 600 watts or so. … An alternator will put out perhaps 20–50 amps at 14 volts… that’s about 600 watts or so.

Will my amp kill my alternator?

Registered. Regardless of how big of amps you have, if you are listening to it without the car running, its going to draw alot of power, and it will kill your battery. Eventually, it will kill it to where it wont recharge. Your alternator strains greatly when you try to charge a dead battery with it as well.

What is the best brand of alternator?

Editor’s Pick: Powermaster Alternators. If you’re thinking about adding any electrical accessories to your vehicle, you are going to want to consider upgrading your alternator from stock to a high-amp unit. … Rare Electrical Alternators. … Eagle Alternators. … A-Team Performance Alternators. … DB Electrical Alternators.

Can an alternator be too powerful?

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. Here’s why: Amperage is basically the amount of electrical current your alternator can supply. And it basically operates off of supply and demand.

How much HP does an alternator draw?

How much engine horse power does the alternator take? An alternator typically takes about 1 HP (horse power) for every 25 amps of power generated. So, a 100 amp alternator will require about 4 HP at full output. Most alternators do not operate at full output for very long.

What causes a brand new alternator to go bad?

Alternators put out alternating current, and the battery needs direct current to charge, so there is a voltage rectifier that converts it, and it can suddenly go bad, too. … Dust and dirt can get into the alternator, and over time cause shorts or wear on the brushes.
