Re: Can I Run an Alternator with Electrical Motor? Yes you can run a Alternator with a electric motor.
Can you run a generator with an electric motor?
YES, but it can only be done long term with an electric motor that is designed to also run as a generator and if the generator will be paralleled with other generation the motor will need to be a synchronous motor.
Can a DC motor drive an alternator?
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 many rpm does an alternator need?
6,000 rpm
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 much horsepower 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 a brushless motor be used as a generator?
Permanent magnet BLDC motors can be used as generators. There is a type of brushless motor called a Reluctance Motor, which has soft-iron core, so will generate nominally zero voltage when spun.
Is an alternator a generator?
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current.In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines.
Will an alternator charge at idle?
Yes, the alternator does charge the battery while the car is idling – regardless of the load on the battery. However, if your electrical use load (radio, lights, fan, etc) exceeds the amount of charge the battery is receiving from the alternator, you will end up with a discharged battery at some point.
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 fast does an alternator have to spin to charge a battery?
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.
How much HP does it take to run a 100 amp 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.
Does an alternator need power to work?
As we know, the alternator provides your car with the bulk of its electricity and helps recharge the battery. But to do all of that, the alternator must first turn mechanical energy into electricity.
How efficient is a car alternator?
The standard alternators generally have a maximum efficiency rating somewhere in the 5560% range and the high-efficiency models are generally in the 6875% range. These efficiency gains are mostly due to using conductors that allow greater fill of the windings in the alternator.
Can a DC motor be turned into DC generator?
Any DC motor with permanent magnets can easily be a generator. It doesn’t matter whether it is brushed or not; brushless motors make great generators but you will need to add a rectifier to get a DC output.
How much electricity can a 12v DC motor generate?
12v DC motor with maximum 1.5A capacity can generate 18W of power. 12v DC motor with maximum 3A capacity can generate 36W of power.
Can you turn a 3 phase motor into a generator?
Yes, a three phase motor CAN be spun to operate as a generator, however, an induction motor used as such will still require a supply voltage, will Have to be spun faster than its normal operating speed and cannot provide reactive power, so would need a capacitor [bank].
Can a car alternator produce 110 volts?
An alternator converts the mechanical energy provided by a vehicle’s engine into electrical energy.Thus the 12-14V DC output produced by your alternator can be converted into 110V AC current.
Can I use a car alternator to build a wind generator?
Turn a car alternator into alternative energy by building this cheap and easy homemade wind generator. If you can turn a wrench and operate an electric drill, you can build this simple generator in two days. You can use any vehicle alternator with a built-in voltage regulator.
How many volts AC does an alternator produce?
An alternator is so named because it produces alternating electrical current. This energy can be converted from one voltage to another using a transformer. Thus, the 12-volt AC output from an alternator can be transformed into 120 volt-AC current.
Is an alternator A brushless motor?
An alternator converts mechanical energy into electrical energy by spinning a magnetic field using a rotor to create energy. A brushed alternator uses carbon brushes to help conduct electricity, while a brushless alternator uses two sets of rotors that spin together to generate and transfer the electrical current.
Can you turn an 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.
