Wiring Keyang Motors

I know there have been several threads about this (http://www.chiefdelphi.com/forums/sh...d.php?t=63669&, http://www.chiefdelphi.com/forums/sh...d.php?t=63697&, http://www.chiefdelphi.com/forums/sh...d.php?t=52350&, to name three), but as I read these threads I don't understand how to execute the instructions posted therein. I have the terminals (PN: 12015860). I think I have the terminal housing, though I'm not sure (PN:12064749). The Keyang Motor I have is PN: 16631023. Here is a link to the Kit of Parts Checklist Revision B to more easily follow this: http://www.usfirst.org/uploadedFiles...klist-RevB.pdf

Anyway, my problem is that I'm looking at the protruding bits from the motor, and the accessible part of the metal seems tiny. Whether I have the right terminal housing or not, it seems like the terminals themselves should be able to fit onto those metal bits, and I tried them every which way but they just don't. Is this a different Keyang than in 2007? Because I remember the terminal housing snapped right on in 2007. And, as an additional question, if it is different, why was it changed?

My eventual solution was simply to solder the wires onto the tiny bit of exposed metal which was available. This seemed to provide a tight connection at the time, though I have concerns about this method. Namely, I can't use an ohmmeter to check to see if the leads are isolated from each other, because within the motor, they aren't. And the space between them is so tiny that I had to use a magnifying glass to check it. Additionally, while rushing the robot into our minivan to take to a playday tomorrow, the soldered ends of the cables came off, which makes me question how tightly they were on there in the first place. There was no hole to thread the wires through, and I didn't have access to the metal they were being soldered onto, so I didn't feel that I could ensure that it was a firm connection.

As I'm looking at the pictures in the KoP checklist it seems like the two motors might have different electrical hook-ups, but I can't really tell. So, any insight on this? I love these motors for their slow speed and high torque, but the hook-up end of it is making me hate them; the CIM motors are so much easier.

Thanks,
Paul Dennis

Re: Wiring Keyang Motors

I think in the past we've used female mini-spade type connectors, similar to the ones to go onto the 20/30 amp breaker panel, only they're much narrower.

Re: Wiring Keyang Motors

I certainly thought about using a crimp connector... but the protruding bit of metal, and I'm not even exxagerating, is around 1mm. I re-soldered the connection and it seems more or less solid, but this may be due to the fact that plastic was fused into it. I'm also concerned about the kind of damage I might do to a motor while holding a soldering iron onto one of the leads for 30+ seconds.

Still frustrated,
Paul

Thumbs up Re: Wiring Keyang Motors

a mentor and I just went to some local autopart stores to see if we could find the right hook-up for the -023 motor and we believe we found a match. If you all still need to find this part, go to your local autopart store and tell them part number EC86, it looks very, very, very close to the hook-up required for it.

Just thought I would let everyone else know in good sportsmanship
