Hi,
Has someone tried before to use a brushless model airplane motor as a semi- HF spindle? They are much more powerful than a dremel and run at high very RPMs. I'd expect that they maybe give low vibration because of the small rotor diameter. Possibly also quieter during rapids (no constant brush-noise).
Could this be done? I'm cutting ply and balsa, so 2HP is overkill for me. My 130W "dremel" has power to spare. Low vibration and noise are my first interest. I'd have to buy one to try it, but maybe someone here knows if an unloaded brushless motor vibrates more or less than a comparable brushed one...
And, what about bearings? I'm thinking of an aluminium shaft coupler between motor and bit (both1/8'). Probably its best to have an extra bearing as close the bit as possible. Would a shielded abec9 skate bearing do, or are they just not up to high RPMs?
Greetings,
John
