How much HP does it take to run a 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 you use an AC motor as a generator?

An induction generator or asynchronous generator is a type of alternating current (AC) electrical generator that uses the principles of induction motors to produce electric power. A regular AC induction motor usually can be used as a generator, without any internal modifications.

How much power does it take to produce 100 amps from an alternator?

It depends on the alternator. 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. If the alternator were 100 percent efficient, it would use 1.6 to 3.2 horsepower, but, of course, they are not.

Does an alternator output 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.

How does a 1/2 HP alternator work?

A motor of 1/2 horsepower capacity is used to drive a combination of belt and pulley drive which form a gear-train and produces over twice rpm at the shaft of an alternator. The intriguing facts about this system are that higher electrical output power can be obtained from the output of the alternator than appears to be drawn from the input motor.

What are the uses of free energy in flywheel system?

Energy becomes free of cost only at a stage after which we don’t have to pay for generation after commissioning the unit. In this research paper, the uses of free energy were noticed by using flywheel system. A motor of 1/2 horsepower capacity is used to drive a combination of belt

What size pulley do I need for a 3600 rpm generator?

1800 RPM / 3600 RPM = 1/2 = Generator pulley size / Engine Pulley size. So, what ever size pulley is selected for the generator, the engine pulley size must be 2 times that size.

What kind of alternator does a Tecumseh 8 hp motor use?

Shown here at the left is a prototype of a project I’m experimenting with for my own use. The AC generator head is direct coupled to the Tecumseh 8 HP motor, and has a belt driven 12 volt alternator mounted to our Horizontal generator bracket which is attached to the motor.
