How much power does it take to turn an alternator?

An alternator takes about 1 HP for every 25 Amps of power. At full output, a 100 Amp alternator will need about 4 HP. For a long time, most alternators don't operate at full output.

Can you turn a car alternator by hand?

If you're talking about a standard automotive alternator that is unplugged and doesn't have a belt to connect it to the rest of the engine, then you're free. After being spun by hand, freely enough, to continue spinning.

How much power does a car alternator draw?

At 105 amps, your alternator provides 1470 watts which is 1.97 hp, or including losses, about 2.35 hp robbed.

How much HP does an alternator take?

An alternator takes about 1 HP for every 25 Amps of power. At full output, a 100 Amp alternator will need about 4 HP. For a long time, most alternators don't operate at full output.

How fast does alternator need to spin?

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.

Using a car alternator with a bike to power my home? How much energy can I produce?!

How much torque is needed to turn an alternator?

If your alternator demand is for example, 2kW, then you need 2.7 HP from the motor to drive it. The details of RPM and torque vs. power you'd have to get from the alternator supplier. Typical alternators were 50-70A at 12V, or about 720W (roughly 1HP.)

Can an alternator power an electric motor?

Answer provided by

The alternator can convert power from internal combustion into electricity, meaning alternators can be used as electric motors.

Can you use a car alternator for wind turbine?

When one uses a Delco car alternator as a wind generator, it is absolutely necessary to modify the alternator to operate at low RPMs. This is accomplished with two intricate modifications: One replaces the stock Delco car alternator stator windings with a stator that has more turns of smaller gauge wire.

Can a car alternator power a home?

The car alternator's role is to produce electricity for your vehicle. So, with minor modifications, the alternator will produce electricity for a home. It charges batteries and runs small appliances or lights. Once hooked up to a lawn mower motor the generator produces a charge like it is still in your vehicle.

How many rpms does a wind turbine turn?

Wind power is generated by the force wind exerts on the blades of a turbine, causing the turbine's shaft to rotate at a speed of 10 to 20 revolutions per minute (rpm).

How many watts does an alternator put out?

Conventional alternator may only produce power for about 500 Watt to 600 Watt. But nowadays, a single alternator can produce power up to 2500 Watt, depending on the power demand.

Why doesn't a Tesla have an alternator?

Electric cars don't have alternators for two good reasons:

Alternators don't generate electricity from thin air. In gas cars they get it from mechanical power, which is supplied by running the engine and burning fuel. EVs don't have engines, so an alternator would be lacking its power source.

How many Volt does a car alternator produce?

A good alternator puts out about 13.5 to 15 volts of electricity. If you're checking the voltage of your car's alternator, it should be at a minimum of 13. Many people don't realize just how important a car's alternator is, as it provides most of the electricity to your car.

Do alternators have to spin a certain way?

An alternator doesn't care which way it turns to charge. The only difference is the airflow on the fins. We use GM alternators from junk yards (cheap and available) on farm tractors and such all the time and they work fine regardless of which way they turn.

Does revving engine charge battery faster?

The battery will charge faster if you rev the engine faster. Why? Because the faster the crankshaft turns, the faster it turns the belt that runs the alternator. And the faster the alternator turns, the more electricity it produces to run all the electrical stuff in the car — and recharge the battery.

Why don't electric cars have solar panels?

These solar panels aren't powerful enough to power a whole car. They've only been utilized to power a few components so far. While solar panels on the roof of a car will never be able to fully charge a battery, solar electricity from other sources is an excellent method to fuel electric vehicles.

Why do electric cars not have gears?

Electric cars don't require multi-speed transmissions because of the so-called “engine” in an electric car, an electric motor. While internal combustion engines require multiple gears with different ratios for power output, electric motors produce a consistent amount of torque at any given RPM within a specific range.

Can you run an inverter off an alternator?

The batteries is what does all the work for the inverter. You can charge batteries with solar, shore power, alternator, or generator. As long as the battery voltage does not drop too low the inverter will be fine.

What size alternator do I need for 2000 watt amp?

To figure out how much capacity or amperage the alternator must deliver, determine how much extra power the audio system demands on top of the current system. For example, if you installed a 2,000-watt amp, assuming a nominal voltage of 13.5V, you'd add roughly 150 amps of demand to the electrical system.

How many amps does an alternator make at idle?

Typically a 12 volt DC unit will begin making power around 1000 rpm's. Remember, this is alternator-not engine speed. The curve is not straight either. Generally 1200 rpm's = 10amps, 1500rpm's = 20 amps, and 2000rpm's = 35 amps, max output is reached at 4500 rpm's (51 amps).

Can a turbine rotation really reach supersonic speed?

The turbine pieces are spinning quite fast, thus its blade tips may be moving at a supersonic speed. But, the airmass may also be spinning modifying the speed of the blades into the airmass. Moreover, the temperature of the air at this stage may modify the speed of sound.

How much force does it take to turn a wind turbine?

Most of what you would call large-scale wind turbines typically start turning in winds of seven to nine miles per hour. Their top speeds are around 50-55 mph, which is their upper safety limit. Large-scale wind turbines normally have a braking system that kicks in around 55 mph to prevent damage to the blades.

What happens if a wind turbine spins too fast?

Speed of a wind turbine

On the other hand, if a wind turbine is spinning too fast it could one cause mechanical damage; and two create a "wall" against the wind to safely spin the turbine to create electricity. Most wind turbines have a maximum speed that they can work at properly.
