Outrunner info??

[BrianG]

Captain: What do you mean by "huh"?

danverz: Thanks. I understand how to figure out the rpms using all the reductions, etc. I just don't know enough about outrunners to know what the "guidelines" are.

jhautz: Yeah, I also knew about the high pole counts and the rpm limit dues to the mass makes sense. Since the weight is so far out, it would also act as a flywheel of sorts as well. I wonder what kind of effect that would have. Those cyclone motors look nice. I guess I'll let you be the guinea pig - it's better on my wallet! :)

Gotta be careful with the Quark programming though:

Note: Please select Out-runner type if an In-runner has 6 poles or above. Also, please select In-runner when using an out-runner with less than 600kv.

So I guess it depends on the poles and/or kv value...

I like the fact that these motors are physically shorter and the lower kv allows me to eliminate the tranny/spur/pinion, which do have some losses. Not to mention it would eliminate any possible weak spots in those areas.
