Re: How to determine "Horsepower" of small electric 12v motors, any help appreciated!

determine

Yes, I am naive about electrical calculations, that's why
I asked for help. And no, I am not selling anything. This is
for my own curiousity and understanding. The phrase
"for demonstrations" was meant to keep this short and
simple. It is for me and some fellow robotics hobbyists.

I can't afford to create a full scale model. I have some
numbers as to how much horsepower is used on full size
equipment which uses gasoline engines and are rated in
horsepower, which is a unit of work (mass, distance, time).

I realize that there are transitional differences in
going from scale to scale, and torque,  horsepower,
power ranges, engine speed, etc. I know what I am
getting into on this level.

I am not an expert, but I need to start somewhere. If the
initial requirements by calculation prove to be too much,
then I will save myself a lot of time and expense. My
hobby is robotics, but I still don't want to waste my time on
something totally impractical.

I don't want to get everyone involved in a discussion about
all the scale transitional differences. But as an example, if I
wanted to create a scale boat, plane, car powered by small electric
motors, and the scale model was exact (I know!), and the
real boat, plane, car is powered by xxx horsepower motors, etc. (not
necessary to point out the differences), I want to determine
if any popular cheap small electric motors could emulate the same
performance. To do that without building the model, I would like
to calculate out the project first on "paper". Therefore, to be able
to calculate a *rough* scale of horsepower supplied by these motors.
Trying to keep it simple at this stage.

Thanks,

Robo

Unless you are buying an electric motor for a boat...then it may be HP
in USA, or kW in the real world
