Question for Patrick

[Just go Play]

When the motors failed during testing was it due to bearings or some other component like magnets seperating?

Well, we've never had a bearing failure during testing. We are using Japanese CNC quality bearings that are rated to above 100K RPM.

It's always a magnet (epoxy, Kevlar wrap, cracking, etc.) failure at high RPM.
