What factors affect the angular velocity of a DC motor (besides wiring type)?)

[Howard]

Going to build a DC motor soon, fastest one wins. Any tips on material type, construction,etc. would be extremely helpful.

 

[OS]

number of rotors, number of windings per rotor, input voltage/current. There are many, many factors.

I'd suggest getting a book on DC/electric machines at the library, this subject is like half a quarter's worth of material.

 

[Howard]

I'm limited to 6/9V, windings unlimited possibilities, wire type unlimited possibilities, 1 rotor.

 

[Howard]

I'm running off batteries, too.

Don't forget the bearings. Magnets should be ridiculously strong, preferably rare-earth or another extreme strength version.

 

[Howard]

Ridiculously strong, eh?

[OS]

what I'd suggest is going to radio shack, buy a slow and fast motor (based on rpm) and do a teardown of each.

This should go into the highly technical forum.

lower turns make more rpm
