Ill get a pictures later but there is a support bearing on the outside just like MT 6880s

Is the shaft held from slipping inside the rotor (can) with grub screws?

Genuine noobish question, why would you want this over something like a TB 6355 which appears to have equivalent torque output? I’m mainly focusing on the difference between form factor, not price.

People who would want this would mainly focus on form factor. You can always get equivalent torque moving up in size but same torque at a smaller size is hard to get.
With a smaller size, you’d get greater clearance.

One major advantage is that this motor has a support bearing. That means the can is supported on both ends. Regular 6355 (and 5055, 5065, and 6374 except the SK3 and SK8) motors have cans that are supported only by the shaft on the butt end - and thus they’re much more susceptible to being damaged by impact or heavy vibration due to the leverage applied to that single connection point.
It’s also smaller in diameter which can allow it to be tucked away into smaller spaces closer to the wheel/truck than a 63xx motor, allowing more stealthy or compact drivetrains, and/or smaller wheels/pulleys/gears.

been thinking these would be good on 4wd for a while now.
The smaller center distance between the shaft and the wheel could allow for a far smaller gear drive, more clearence and more compact. plus in 4wd configuration this would be plenty of torque. The big end bearing is also a big selling point for me keeping the long motor bell running true and keeping all the shit out.
if only they were easier to buy

What’s did they work out a unit?
With shipping like that I’d be open to any group buys

Benjamin Vedder told me a long time ago that the FOC calculates the resistance of one phase of the motor (from one lead to the center of the motor), meaning the actual resistance from lead to lead (and the inductance) is double what the FOC detection says. In this case, 26.1 milliohms is 0.0261ohms (one phase) or 0.0522 (two phase / lead to lead). It’s most likely still the case, so if you use 60a motor current limit in BLDC the heating at that current works out to:
60a^2 * 0.0522ohm = 187.9w ohmic heating

do the popular sealed maytech motors have dual bearings as well?

No, they don’t to my knowledge. Very few motors do (I only know of three off the top of my head: SK3, SK8, and this 5095). There’s quite a bit of extra complexity and space involved in fitting the extra bearing, and for airplanes (That’s what these motors evolved from) you don’t really need it because airplanes don’t generally spend much time rolling down bumpy roads.

aren’t you also trading off though for a wider wheelbase because these motors are longer?

Yeah, that’s true too.

Only if you put two on each truck. I have more skates with 1 motor per truck, or 1 motor period.

good point, forgot about that =/
I’m just waiting to see how @deckoz mounts his and I’m gonna copy it 
I have no shame. I want a good setup, and I know I’ll get one if I copy him

Do you mean dual diagonal? I’d be interested to see a build thread on that if you don’t mind.
