The humble automotive alternator hides an interesting secret. Known as the part that converts power from internal combustion into the electricity needed to run everything else, they can also themselves be used as an electric motor.
Can you run an alternator with an electric motor?
You can use a DC motor to drive an alternator in order to invert a DC energy supply into AC. But you would be setting up a system with needless mechanical complexity. It would not be economical to needlessly drive an alternator by an electric motor. Magnetic force in an alternator causes a mechanical resistance.
How much power can an alternator produce as a motor?
How Much Power Can An Alternator Produce As A Motor? The power output of a conventional alternator is usually between 500 and 600 Watts. In today’s world, a single alternator can produce power up to 2500 Watt, depending on the power demand.
Can you use an alternator to generate electricity?
Yes, alternators generate electricity most efficiently when driven by an internal combustion engine. Their application in a motor vehicle is common. Also as a stationary power source to charge batteries for off the grid power.
How fast does a car alternator need to spin to produce power?
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.
Can you power a house with a car alternator?
Yes, but it gets complicated an expensive. A standard car alternator is only 50–70amp at 12v. This is only about 4 amps. There are very few device in your house you can power this way.
Can an alternator charge a Tesla battery?
No, Tesla and other electric cars don’t have alternators. They have DC to DC converters. This converts high voltage DC from the battery pack to low voltage (13–14V DC) to charge the 12V battery.
Does an alternator produce AC or DC?
Car batteries operate on one-way direct current (DC) electricity, while alternators output alternating current (AC) electricity, which occasionally flows in reverse.
Can an alternator produce 240 volts?
Therefore, you need an alternator that will produce at least 125 Amps. In reality, you need more than that, in order to still have 1500W after you get done converting it to 240V. Fortunately, without trying too hard, I could find 200A, 250A, and 300A (2400W~3600W) alternators … so this is definitely possible.
Can I use an alternator for a 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. … One replaces the stock Delco car alternator stator windings with a stator that has more turns of smaller gauge wire.
How much horsepower does it take to spin 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.
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.
How many volts does an alternator produce?
A good alternator should put out between **13.5-14.5 volts. Stress test the alternator – Place a load on the alternator by turning on the headlights, the radio and the air conditioning. The voltage should remain high with these circuits on.
