Motor shaft came through the endbell on CC 2200kv. Why?

Usually, this type of failure occurs when the motor is too hot -- the epoxy holding the rotor on the shaft softens at about 180C

But it can happen if the rotor is incorrectly built as well.

Contact tech support, and we'll send you a new rotor for the motor.

Thanx!

Thanks Patrick. It is great that you frequent the forums.

What about the endbell? Does it actually have a hole in it or did the shaft chew through it? If so, what do I do about the hole?

Should have mentioned that the motor comes off the track after a 20 minute main at 170 degrees at the hottest location, cooler on other parts.

I run 4S batteries and have to do a battery swap to make the 20 minutes. Seems like once the motor gets to its peak temp, it stays there. I get the same final temp during qualifiers too.

The end bell is fine -- that's just a sticker over the bearing. :)

Awesome. I'll just put some clear box tape over it to keep dirt out.

I emailed the tech I've been corresponding with to ask for a replacement rotor.

Thanks again Patrick.

Absolutely. Got the email from the tech after lunch today that the new rotor is in the mail, even got the tracking number.
