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 an alternator run an electric motor?
The alternator will supply the power to the motor which will get less than it needs to run full, which will provide less power to the alternator then giving even less power to the motor, the cycle will keep going (depending on how much momentum it has and how fast it was going) until friction takes over and stops the …
Why can’t a electric car recharge itself?
Yes, a self charging electric car is simply made using in wheel hub motors, supercapacitors, and a generator. … But apparently the amount of energy used to produce the energy for charging the second battery would cancel out the energy produced.8 мая 2016 г.
How much HP does it take to turn an alternator?
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.
Is an alternator considered an electric motor or an electric generator?
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.
What is the minimum RPM of a 12v car alternator?
How do I know when my alternator is bad?

Do electric cars charge while driving?
A connection would be made between the trailer and car to allow charging while driving. The advantage is in keeping the purchase cost lower. Some electric car makers advocate for large battery packs with 300-350 miles range along with a fast charging system allowing for a 1-1.5 hour recharge time from empty.
Do electric cars charge as they drive?
Applied to automobiles, it makes it possible to charge the battery of an electric car by parking it over a special charging pad. … Dynamic induction charging works according to the same principle, only with a moving car. In this setup the car is driven over a series of emitter coils set into the road.
What happens if electric car runs out of power?
We don’t recommend running you electric car to empty. Manufacturers warn that this can damage the battery. Running completely out of power, or ‘deep discharging’ as it’s known, can cause the battery cells to deteriorate and reduce their performance in the long run.
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.
Does new alternator make car faster?
Your old alternator was not charging properly.To answer your question no it cant make your vehicle go faster. It” connected to the w speed connection point that will give a person true indication of engine speed we use it on generators a lot.
Can alternator affect horsepower?
Just for a rough idea, a typical alternator output is 100 to 200 amperes, or 1200 to 2400 watts. That’s 1.6 to 3.2 horsepower. … That’s 1.6 to 3.2 horsepower. If the alternator were 100 percent efficient, it would use 1.6 to 3.2 horsepower, but, of course, they are not.
Is a car alternator AC or DC?
You may even know your battery provides DC current that the car uses, but your alternator generates AC current. … Cars use DC, Direct Current. That’s the type of electricity produced by batteries, and it flows in one constant direction.
Can a car run without an alternator?
The car will only run until the battery is dead if the alternator quits, which might be 5 minutes, might be 30.
How much voltage does a car alternator produce?
The alternator is designed to keep the battery charged to at least 12.55 volts, with a maximum of approximately 14.5 volts. The amperage output is usually listed as the maximum output of the alternator.
