Short version:
Kollmorgen 400w motor for a skateboard: http://goo.gl/M92Rx
- I want brushless for it's increased efficiency.
- Seems to be the most widespread brushless motor for bikes/scooters. Which means reliable?
- 5" diameter....should work depending on my wheels.
- 24v, 30A max, 400w
- Built in ESC; 5k pot
- Can't find any info about torque/RPM (generally ~3500RPM)
- Not sure if the ESC has a "break" function where the motor gives resistance to rotation. Does it need to specify this?
- I really wan't a break function to go down hills with...
- Planning to retrofit an E-glide skateboard with this motor.
I wanted to know others thoughts regarding my ideas. I appreciate any/all input.

___________________________________________________________
So I've recently been turned on to the world of electric skateboards after riding one. I want a commuter board: lightweight, smallish (~36"), goes up hills, ~10mi range.
If I were to buy one, three options:
- E-glide 42" special - http://goo.gl/lExSt - Excellent board, superior reliability, $700, 50lb
- http://www.metro-board.com/ - Short board, wireless controls (eh...), $900 (too expensive for something that may break)
- Z-board - the new guys from kickstarter. A little heavy (~35lb), otherwise perfect. New guys/unsure reliability...$900
So I've decided to give it a go myself. Since I live close to the E-glide shop and they've been doing this for a decade, I'm planning on just picking up the board, trucks, motor mount, batteries, under-board batt bay from them.
The ENORMOUS majority of electric bikes, scooters and skateboards are using brushed motors. Is this only due to cost? I mean brushless isn't really that much more expensive when you're using custom made electronics in large quantities like E-glide does. I'll ask them this next time I go there.
Next, I'm thinking to maybe possible to swap out the E-glide motor for a Kollmorgen 400w motor: http://goo.gl/M92Rx
My only reason for choosing this motor is because it seems to be the most widespread brushless motor for bikes/scooters. That just means reliability to me. It also happens to have an ESC built in which simplifies everything. I see many using hobby motors...cool, but questionable since you basically end up with an RC car you happen to be able to stand on. Not to mention the electronics will likely fail due to misuse. Not an option for this project. I also do not like wireless.
For some reason, I can't seem to find any hard specifics about this motor. Nothing about torque, not much about RPM, nothing about the ESC other than it draws 24v 30A max. I note that it's got a 5" diameter which may or may not be a problem depending on the wheels I use. The other thing I'm concerned about is that I really want a break function on the skateboard. I believe the "break" is simply off on the motor with this particular model. I'm not quite sure what that means because when I rode the E-glide things, off was pretty much break and they said for electric there is no 'coast,' you either gas it or not. Coast functions are programmed into other ESC's if they have them.
