Hi jeremy callahan,
There was a documented manufacturing defect which affected some BAG motors. We at VEX/IFI worked very closely with FRC teams, our motor manufacturer, and FIRST to identify the problem and provide a retrofit to teams.

http://content.vexrobotics.com/vexpr...s_20130411.pdf

In addition, we've ensured that this problem will not happen moving forward. 100% of BAG motors in our warehouse have been retrofitted, and ALL of them were dyno tested in-house to ensure performance within 10% of our published spec. (It turns out, all of them were within 5%.)

If any team experiences a problem with a BAG motor, I hope they will immediately contact our customer support team by emailing prosupport@vex.com or calling 903.453.0802 We pride ourselves on our customer support, and want to "make things right" if you have an issue.

-John

yash101,
I'm sorry to hear your team had BAG motors fail. Did you contact our customer support group?

Based on some of the other comments in this thread, it sounds like it might have had something to do with your application, but of course we'd be happy to talk it through with you and your team.

If you suspect there is some problem with the BAG motor in general, we want to help resolve it, or identify what is really going on.

Take Care,
John

Re: CIM Motors reusable?

Thanks. I'll talk to my team about it. Right now, it isn't too big of a deal anymore. All our other vex products perform the way they should!
