OK, so the light mover came in last week. It's going to do a great job of giving me the coverage I need on a TEN foot tank with only three LumenBright lights. The only problem was the speed of the mover. I wanted something that I wasn't really going to notice moving, which wasn't the case here.
After doing a little research, I found that the motor is made by
Hurst Manufacturing, a division of Emerson Motor Technologies. By looking around on their web site, I was able to find the
series of the motor that was used with my light mover. And they have a similar unit that moves at 1/10th of the speed! I ordered a replacement motor which came in today and I was ready to swap out the slower motor with the one that came on the
light rail 3.5 system.
It turns out that the motor can't be removed from the light mover as easily as I thought. It is riveted into the mover and removing it wasn't going to be simple. After looking at my options, I figured the most obvious one would be just to switch out the gears in the gear box. Then I wouldn't have to deal with any wire changes (I would use the existing motor) and I wouldn't need to drill out the rivets and have to figure out a way to reattach the housing to the gear box. So I asked a guy at work to help me, since he's much more knowledgeable with electronics & motors than I am and I wanted validation that this was going to work.
So we carefully removed the housing of the new motor's gear box to reveal the gears:
As you would assume, there are a LOT more gears in this housing than in the original motor's gear box. We wanted to keep them in order so we carefully placed them on a paper plate in the same general location, along with a number to represent what order they were taken out:
which in turn would tell us which order they needed to be put back in.
I am happy to say the transplant was a success. I mounted the motor back on the rail and it creeps along at a snails pace. I don’t think you’ll really notice that the MH lights are moving once everything is installed. Thanks to Brian for helping me during this process. (he did most of the tedious stuff) Now I have to wait for the trolley to come in that I ordered and I’ll get the lights working as expected. (more pictures to come when that happens)
Later!
