Relation between RPM, coils and kW-output in electrical generator

[badshot]

Hi,
new to the forum here
I have this bike-engine here and I am thinking whether it would be possible to mount it to an electrical generator. The thing is it easily hits RPM's up to 13000.
My question is if I make a magnet spinning at let's say 10k rpm what poweroutput are we talking then. Could it melt the coil, how densly winded does that coil have to be and so on.
I am not interested in a 220V home and office output. Its for transfering mechanical input to mechanical output via electricity. This is the plan:

engine--electrical generator----------------electromotor--wheels

Is it worth considering or not?

thx in advance,
Bert

It is definitely worth considering, depending on the size and power of the engine. The output of a generator depends on the speed at which its magnets are spinning and the type and number of windings in the coils. If the engine is able to reach up to 13,000 RPMs then there is potential for a good amount of power output from your generator. However, it is important to note that the higher the RPMs, the more likely it is that the coil could overheat and melt. To prevent this, you should use thick gauge wire for the windings and ensure that the windings are spaced out enough so that the heat can dissipate. Additionally, you will need to make sure the generator is properly cooled to prevent any damage.

Hello Bert,

Thank you for your question. The relationship between RPM, coils, and kW-output in an electrical generator is a complex one and depends on several factors. RPM (revolutions per minute) is a measure of the speed at which the generator is rotating. Coils, also known as windings, are the wires that are used to generate electricity in the generator. And kW-output refers to the power output of the generator in kilowatts.

To determine the power output of a generator, you need to consider the rotational speed (RPM) and the strength of the magnetic field generated by the coils. The higher the RPM, the higher the frequency of the electricity generated, which in turn can increase the power output. However, this also depends on the strength of the magnetic field, which is determined by the number of coils and the density of the windings.

In your case, if the engine is capable of reaching 13000 RPM, the magnet spinning at 10k RPM could potentially generate a significant amount of power. However, it is important to note that the power output also depends on the efficiency of the generator, which can vary depending on the design and quality of the components.

As for the risk of melting the coil, it is possible if the coils are not properly designed to handle the high RPM and power output. The density of the windings also plays a role in this, as a higher density can help dissipate heat more efficiently. It is important to consult with an expert or do thorough research before attempting to mount an engine to an electrical generator.

In conclusion, your plan of using an engine to power an electrical generator and then an electromotor for mechanical output is definitely worth considering. However, it is crucial to carefully consider all the factors mentioned above and ensure the safety and efficiency of the setup. I hope this helps. Best of luck with your project!
