As you can see, the ring holding the magnets in place has come loose. I can hammer it back into place then I start riding to about 70% throttle, motor screeches horribly and then it all comes loose and grinds on the other part of the motor.

What can I do/use to re-secure the ring into place? This motor gets quite hot under load (not worryingly hot) but hot enough to loosen most glues I think.
Look at the lower part of the magnets. They’ve all slid up:
I’ve never potted/glued the magnets but think it was wanderer who did. Never had one come loose yet. If you don’t hear from wanderer rcgroups.com people have threads on the subject.
The tesla motor windings are potted.
I used two part epoxy. Couldn’t tell you which one exactly. I think it held for a bit but I did eventually have to buy a new motor. Not 100% sure if that was because of this issue or because I had to for other reasons
