Re: Buggy BAG Motors
All,

It is imperative that you send the failed, or suspect failed, motors back to us. So far we have only received 3 motors that have actually shown the failure mode described.

I need to send samples of failed motors to CCL this week to get their opinion on root cause. VEX has already formulated our opinion, but we want confirmation from CCL.

Richard is right no with the suspected failure mode as the physical evidence I have so far indicated a winding tension problem.

More importantly, the only failed motors I have are from batch 2491. I do not have any failed samples from batch 2493.

We want to get to the bottom of this as soon as possible but need failed motors back.

To answer an earlier question, no we have not had any reported failed MiniCIM motors other than a couple physically damaged during shipping. To state that all of the VEXpro motors are under suspicion is jumping to conclusions without fact. Please keep this discussion to facts only so we can get to the bottom of this.

Thanks,
Paul
