like a small electric motor

And how can i make it?
Like step by step instructions.

Well, at this point in time it would be like making a wheel that is very, very round. I'd buy one. I don't know how fast you want it to go but a dremel motor will run around 30,000 rpm.
There is such thing as air bearings. If you want some real speed may have to go to those to keep bearings cools. Look up gas bearings.

Getting a motor to spin fast is easy. Most DC motors will self destruct from high rpm if the field and armature are connected in a series configuration as opposed to shunt and no load is presented to the shaft.. In this arrangement there is little torque output but RPM's soar. With permanent magnet motors fewer turns of heavier wire in armature windings will increase speed. Weakening the field here is not an option unless you can drain some field strength by applying an AC field near the motor field to reduce its strength. Anytime fields are weakened to increase speed torque is reduced.

Round so so so so so many coil , and connect much much much much larger voltage !

why make it? buy a Dremell they run 25,000-30,000 RPM's

Attach it to a very very very very very superdooper mega big WINDMILL... that should do it... stay cool... c",)
