How much horsepower is required to turn an alternator?
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..
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. … FOR YOUR ALTERNATOR, WILL NOT BE AS EASY TO FIND.
How much torque does it take to turn an alternator?
Well-Known Member. Good info tcmtech. Just for a point of reference, a standard automotive alternator puts out 60A @ 14V = 840W. 1hp = 746W, so it takes over one hp to turn your car’s alternator to full output, not counting losses in heat or the belts…
At what RPM does a alternator charge?
These rpm, along with the pulley ratio, directly affect an alternator’s performance and life expectancy. 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 many amps does an alternator put out?
Most late model alternators produce 120 to 155 amps or more. Current output increases with engine speed, from around 20 to 50 amps at idle up to the unit’s maximum output at 2,500 RPM or higher (refer to a service manual for the exact charging output specifications for your vehicle).
What RPM is needed for electricity?
1,000-1,800 rpm1,000-1,800 rpm is the rotational speed required by most generators to produce electricity. The high-speed shaft drives the generator which produces AC electrical current. Power cables transport the electricity to ground level.
Is 15 volts too high for alternator?
Higher than 15 volts indicates a fault in the charging system’s voltage regulator or related circuits. If it’s substantially excessive, this can cause electrical system and/or battery damage. You mentioned your voltmeter runs at about 15 volts most of the time.
How do I get more amps out of my alternator?
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 do I calculate my alternator rpm?
Speed(RPM) = Frequency(Hz) X 120 / Poles = 100 X 120 / 12 = 1000 RPM.
How many amps does a 12 volt alternator put out?
At 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.
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 can damage an alternator?
Driving a vehicle through water that is deep enough to splash or flood the alternator can damage the alternator shaft bearings and possibly the brushes and electronics inside the unit as well. Water can also cause corrosion that over time will damage the wiring and bearings inside the alternator.
Can an alternator run backwards?
Yes, you can, on most all alternators. I installed a FWD Buick 3.8 into a 4wd S-Blazer, flipped the intake 90 degrees (too many mods to state, but never again), and the only way I had room for everything was to run the alternator backwards (CS series alternator).
Can a car alternator power a house?
Yes, of coures. Alternators can be used to generate electricity, but the alternators are noisy. If there is a short-term power failure, or the family just needs lighting, you can use general lighting, such as flashlight.
How many watts does a 200 amp alternator produce?
2880 wattsA large alternator can be 200 amps or more. 14.4 volts x 200 amps = 2880 watts.
