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.
How much power can an alternator produce as a motor?
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.
Can an alternator charge an electric car?
Yes, an ‘electric’ car could be equipped with an with an alternator (generator) to charge the batteries. An engine of some sort would be required to drive it and that engine would need fuel.
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 an alternator power a house?
You can use car alternators to power a home. One method of doing this is to use the alternators to recharge storage batteries. These batteries could then be used to power an inverter, which would produce the AC voltage needed to run the house. … Connect the alternator and gas engine together using a V-belt.
Does an alternator make 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.  So prior to going to the voltage regulator, power intended for the battery goes through a diode rectifier to turn into DC.
Why can’t you put a alternator on an electric car?
An electric car doesn’t have an engine or gas/diesel fuel. Instead, it has an electric motor and rechargeable battery. … Essentially, using an alternator powered by an electric motor, we could only ever make a smaller amount of electricity than we started with.
Why can’t electric cars have solar panels?
Electric cars do not have solar panels because when solar panels are on cars, they are only converting 15%-20% of the energy from the sun. The solar panels would only give about 3 miles of energy in one hour of charging. This is very inefficient and currently doesn’t make sense to use on electric cars yet.
Is an alternator a motor?
In simple engineering words, the main difference between Alternator and Motor is, the alternator converts mechanical energy into electrical energy whereas the motor converts electrical energy into mechanical energy. … So motor and alternator exactly opposite to each other.
Can DC motor generate electricity?
Originally Answered: Can we use a DC motor for generating electricity? A DC Motor can be used as a generator. You will need a prime mover such as a turbine or an IC engine or even hand cranking to rotate its shaft. based on its design (RPM vs voltage), it will generate DC output voltage.
Can I use a car alternator as a generator?
Another method of running your house off of a homemade generator setup involves a bank of batteries, power inverter(s), and using automotive alternators in a small backyard windmill or other power source like a lawn mower engine to turn the alternator. … Using found parts, or buying a used mower engine is closer to home.
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.
Can a car alternator power an inverter?
The average size alternator used in a vehicles’ DC charging system is about 100 AMPS DC. This can power an inverter that will deliver about 1,200 watts @ 120 VAC.
How fast does alternator need to spin?
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.
