The rotational speed of the alternator rotor is expressed in revolutions per minute (RPM). And RPM is said to be low when RPM is between 100 and 450.
Is it possible that with low RPM we can make 60Hz AC voltage? This article will give you the answer. And the best choice to buy, and make your own generator for the home.
1/ Basic structure of AC Generator - What is the basic structure of an AC generator different from a low RPM generator?
The alternator consists of two main parts, the rotor and the stator. On the rotor there are permanent magnets, and on the stator there are windings. The coils can be connected in different ways. A typical example is a three-phase star generator. Then, 3 coils will have 6 wire ends, with 3 coils connected to a point, and the remaining 3 coils corresponding to 3 voltage phases.

The basic construction of a generator with a low rpm has the same basic structure as above, but with a larger number of magnets, and a larger number of coils. And the way the windings are connected is also different, can produce output voltage is single phase, or 3 phase, or more.

The basic difference: The number of windings on the stator and the number of magnets on the rotor of an RPM generator is usually larger than that of a standard generator.
2/ Standard rotational speed of alternator
The standard frequency of AC that Nikola invented has the best operating frequency for transmission and efficient use of electricity is 50 or 60 Hz. Therefore, the rotor's speed per minute and the number of pole pairs (south and north) of the rotor's permanent magnet board will determine the frequency of the standard AC voltage.
A 2-pole generator generating 60 Hz has a motor speed of 3,600 rpm. To change the output frequency to 50 Hz for the same generator configuration, the motor speed needs to be reduced to 3,000 rpm.
The general formula for frequency F = (V/60).P , where V is the speed rotation in revolutions per minute, and P is the number of poles of the permanent magnets on the rotor.
Similarly, for a 4-pole generator, a motor speed of 1,800 rpm produces 60 Hz power. Reducing the motor speed to 1,500 rpm produces 50 Hz power.
Thus, to increase the frequency of the current, with a low rpm, then we have a simple solution, which is to increase the number of pole pairs of the magnet on the rotor.
A generator with a low rpm usually doesn't give specific frequency specifications. Because this is a generator that receives kinetic energy in a very real form.
Standard rotational speed of 3-phase AC generator:
According to the formula F = (V/60).P
We will calculate V to get a frequency of 50 or 60 Hz, with P = 3
- With F = 50, Then V = (F/P).60 = (50/3).60 = 1000 RPM
- With F = 60, Then V = (F/P).60 = (60/3).60 = 1200 RPM
3/ Low RPM generator for sale
China is a very famous producer of rare earth magnets. The powerful magnet determines the voltage and performance of the generator.
You can purchase a Low RPM Generator on the online marketplace of Amazon, China, USA, or at your local electronics store.

4/ Application of low rpm generator
Low rpm generators are often bought by people to make their own generators. Some businesses also buy to create backup generators.
Common applications of low rpm generators:
Direct use: even if the frequency is not up to the standard 50 or 60Hz, the generator output voltage is still used for induction motors, although its efficiency is not high.
Indirect use: The output voltage is unstable because the rotor speed is not stable. Because the source of kinetic energy in nature is not stable. So it will be used to go into the converter named inverter. After passing through the inverter, the voltage and frequency can be adjusted arbitrarily. Inverter generators with gasoline fuel also use this method.
Use to create free energy: this is a method of combining 2 or more agitators, to create free energy. This method orthodox science does not teach! It doesn't exist in academia today. Because more than 100 years ago, Einstein put forward the theory of relativity and negated the so-called Ether. Relativity is an academic scam, it has been invested by capitalism to reign in science.

Applications beyond mainstream science of low rpm generators:
✔ The Real Nature of Tesla AC Generator
✔ Combination of induction motor and alternator
✔ Combination between generators
✔ Or maybe called Overunity for the system. Mother Nature doesn't care about people calling or naming phenomena. Overunity or Free Energy, or Zero Point Energy (ZPE) are just a few different words
