Diffrunner concept

Three bearings to support the diff/endbell. A large bearing on the mount side, one at the center to the shaft, then the last bearing would support the end of the diff.

Oh, that sounds good. But what is the second bearing supporting? Doesn't make sense putting a bearing in the middle if it's to support the rotor? Am I missing something?

It's to eliminate flex.

You don't want the diff housing and the larger span trying to tame the magnetics of the motor, do ya?

Hmmm............trying to visualize everything here.

If the diff housing were thick aluminum, and the bearing on the diff end was enlarged, then the center bearing wouldn't have to support the endbell at all.

Two shaft bearings inside the motor would help hold everything true.
