Outrunners supported/held by the shaft?

[zeropointbug]

Thanks guys, and thanks redshift for posting that... so are ALL outrunners assemble that way? If so, then that is perfect for the design, of course we just have to be sure...

BTW, I call it the "diff-runner"

That question is better left to the OR experts.

Sikeston..... I see you

LOL

I was processing.

Take a look at the 3032 Scorpion Motors on the website.

Here's talk about the bearing. Without something like this, you will have problems with flexing.

"The new version 3032 motors now have an extra ring bearing to support the back end of the rotor can for rock-solid stability. This prevents the shaft from flexing under load, and maintains the airgap between the stator and the magnets under all operating conditions."

If the Shaft will flex on longer endbells, your diff cup WILL flex for sure.

This is do-able for sure as long as you consider gear ratios and roll out in your setup.

By connecting the endbell to the diff, you're adding a flex point.

You can get by with this, as long as you use a motor with the endbell bearing. It's a press fit, but will prevent the magnets from contacting the stator during hard acceleration or braking.

Does your motor have the larger press fit endbell bearing?
