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.)

How much force is needed to spin an alternator?
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.
How fast can you spin an alternator?
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. The speed of an alternator is different for different type of car. The speed of an alternator depends on the speed of the engine.
What spins the alternator in a car?
When the battery initially powers the car, the alternator belt, or V-belt, spins the pulley on the alternator, causing the rotor inside the alternator to spin very quickly. This rotor, which is basically a magnet or group of magnets, is situated inside a nest of copper wires, which are called the stator.
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 amps does alternator charge battery?
A: Charging time depends on the battery and the charger. For a battery being charged by the car's alternator it can take an hour of driving to get it fully charged. Car batteries range from 40AH to 110AH, and alternators range from 45 amps to 200 amps.
Can a car alternator power a house?
The total power (in watts) from typical car alternator is too low for typical whole-house power supply. You can buy an inverter that provides 120V AC power from a car but you probably won't have enough amperage to run a whole house-- at least not seamlessly.
How much drag does an alternator produce?
Yes, an alternator will put additional strain on the engine but it is insignificant relative to even the internal drag on the engine. If you convert watts to horsepower the conversion is about 1 horsepower = 750 watts.
Does alternator increase horsepower?
In addition, says Basner. “On some applications, a high-amp alternator can actually add horsepower to your engine's performance.” Sure, it's nominal, but, when it comes to horsepower, every bit helps. “Most alternators are only about 75 percent efficient.”
How can I make my alternator spin faster?
You'd be better off using a smaller pulley on the alternator, or a bigger one on the engine. It'll make the alternator spin faster, producing enough power at low engine speeds. It's the simplest, cheapest, most reliable solution.
Can high rpm damage alternator?
TOO HIGH OF RPM WILL DAMAGE ANYTHING. INCLUDING ALTERNATORS. YOU IMPORTANTLY MUST BE AWARE THAT IF THE ALTERNATOR IS BELT DRIVEN, THE DIFFERENCE IN SIZE OF THE TWO BELT PULLEYS MIGHT HAVE THE ALTERNATOR TURNING FASTER THAN THE ENGINE RPM, MAYBE MANY TIMES FASTER.
What is low rpm alternator?
Typical conventional alternators generate about 30% to 35% of their rated full output at the same 600 engine RPM's. ... Eco-Tech patented low RPM alternators excel in applications where high electrical output is needed at low engine RPM's.
Is your alternator supposed to spin?
If you are referring to a standard automotive alternator that is unplugged and does not have a belt coupling it with the rest of the engine, then quite freely. Freely enough, in fact, to continue spinning for a bit after being spun by hand.
What is the alternator pulley?
The alternator pulley allows the V-shape or serpentine belt to spin the alternator and is driven by the engine's accessory drive system. ... When the engine remains idle, it remains at enough speed to produce sufficient power for maintaining the battery's charge.
Does the alternator affect acceleration?
The falls in the electrical power of a broken alternator can cause a malfunction of these systems, leading to a malfunction of the engine. Symptoms will be the slowing down, the failure, the poor acceleration, the hesitation and the stalling.
