HumboldtRc said:What does "kt" stand for? torque?
It the motor's torque constant. It is in units of Newton meters divided by amps.
If you were to multiply the motor current by this constant, you'd get the torque.

I must say, it's the coolest looking motor that Hobbyking sells. It's all blacked out and anodized - very much a departure from the chrome cases of the others.
But, in classic HK fashion, it's a little lacking in legitimacy. The rotor case is aluminum! I can't see any steel backing or magnet ring. The magnets appear to be glued right to the Al case, and as a result, the thing can pick up a set of 10 inch lineman's pliers and hang it in midair. Alot of flux is just going to waste there.
Though constructionwise, it's pretty solid. The can bearing is a 6814 type, 70mm bore, and the shaft bearings are 12mm. I can confirm the ridiculous no-load amps - measured at 16-17 amps at 12S LiFe. 24 tooth stator, 28 magnet poles.
I think that EVwise it does not offer significant advantages over the 80/100 because of the Al case. It's a very fast motor for sure.
However, if someone were to make an identically dimensioned STEEL can, it would be a torque monster.

swbluto said:How would steel affect flux wastage and efficiency? I guess I understand the legitimacy of steel if you're building combat bots.
You'd feel it a lot more, if it wasn't steel :wink:markobetti said:Its steel and very good magnetism on steel, thats why you can feel magnetism at the outer can , and no problem with putting external hal sensors to sense the magnets.

This can mean just about anything. lol
