What's the smallest/lightest motor you have been able to use to climb?

I disagree that it should be treated as a 775 pro. These things are monsters at dissipating heat through the face plate. That said, they do have a relatively low thermal mass.

Were you really stalling at 12V? Because that would have been 100A, which the spark max current limit should have protected it from. I’m curious what you had it set to. If it was the default 80A, then I’m not surprised it popped like a bubble.

We briefly used a bag motor in 2017. I think it was geared 300:1.

We are running a neo 550 at a 50:1 ratio, the winch is 1" webbing on thunderhex so it varries between 1/2 in and about 1 in diameter. We did smoke one motor at comp but that was because the climber was stuck down. other than that it has worked great, not sure on the exact time but definately sub 3 seconds.

This is late, but of course 254 recommends a Falcon…

I mean it’s the best motor for the job.

I know, but 254 could probably pull it off with anything (reasonably).

A Falcon or NEO are the best motors for any application unless the application requires very tight packaging and then you might want a neo 550. Imo, brushed motors aren’t really worth it. Brushless is lighter, more powerful, and cheaper.

I thought that NEO 550’s were brushless motors as well?

50

Yes, they are. Which is why i said brushed motors aren’t worth it anymore.

51

Yeah, I see it now. I thought that you were implying that NEO 550’s weren’t brushless. :blush:

I do still like the brushed motors for simple tasks where an encoder is not necessary or super easy. A mechanism can be prototyped with only a battery and variable resister (aka- cut off cordless drill).
And does a 9015 count against the CAW?
I never want to use a brushed motor again where there is a ‘hold position’ scenario like a winch.

53

Yes, there are no 9015 motors in either KOP tote or FIRST Choice. If you purchased one this season with your AM voucher, then they don’t count towards total BOM cost.

54

I think that a 9015 would count against it since it would most likely cost more than $5.00… :money_mouth_face:

Thanks. I didn’t inventory the KOP, but see we have a drawer of them from somewhere.
