The motor hangs outside the tank, on the lip, so Im not worried about it. Oceansmotions have exposed motors in closer proximity to saltwater.
I dont have an exact model number, the box simply sez 1rpm hansen synchron motor, the motor itself does have more...
Around the motor it is stamped...630 110V 60 CY 4W 1RPM K12RC-6 7-79

I let it run a few hours, and although it is very hot, it doesnt seem to be enough to melt the acrylic. None the less, I am looking for another motor... These came to me 3 for $10, but they are 1rpm. I would rather they had a 1/4" shaft rather than the 1/8" one that they have, and of course, much cooler. But were on the right track here...
D, I recall you ordering these motors for Surplus Center:
https://www.surpluscenter.com/item.asp?UID=2006031613352805&item=5-1563-A&catname=electric
Did you ever get around testing them? How do they hold up as far as heat?

I didn't get a chance to test mine last night, I'll try and remember at lunch. I'll let it run for my full hour lunch, minus five minutes drive time, and report back.
I like the design, I bet it certainly cost a lot less than the $24 I spent on mine. It doesn't seem any different other than you diy a box, and used rotating disks. I thought about disks, I did know that would give you a better rotation range. I was afraid the weight of the mj on the end of my joints wouldn't hold, I guess I just wasn't sure my seam would be strong enough to hold long term. What kind of glue did you use? It also would be a really tough fit inside the box I used. Yours looks to be more like 5x3
I did my first water test last night in a 20g. I made this for my 120, so it sets deeper than it would if I had made it for a 20. But when it hit the end of full rotation and was aimed cross tank, at about 35* with 45* be directly into the wall, it was digging a huge hole in the sand on the other side. I'm not so sure I could see a use for more than about 45* rotation if you have sand in the tank. If you get to the point you are aiming directly across the tank I think you would murder your sandbed.
I also don't like the idea of 110v direct main current unsealed anywhere near water I stick my hands in. It seems to me if you where to inclose yours it would be something like 5x3x2, which is a good bit bigger than the 4x4x2 box I used. I bet with tweaking it would fit in 5x2x2 but I don't think you could get that in a 4x4x2 box. Not without reducing disk size anyway, which puts you back to a custom box, and I didn't want to deal with that on my first one.

I use weldon #3 to bond the acrylic to itself, and #16 to bond other plastics to acrylic. The extreme angle is nice if I were to mount the powerhead in the center back of the tank...then it blows down one end of the tank and then the other as it sweeps around. I will most likely use it in a 90 degree setup though, placing the powerhead at the end of the tank.
I also considered the 'water damage' issue some more with the motor being exposed. I figure, I can easily make a small acrylic box to encase the motor alone out of 1/8" acrylic. That should be plenty, and then Ill have to drill vent holes anyways if I cant figure out this heat problem.

Ok I tested both the 2.5rpm and the .75rpm for 40 min at lunch.
2.5rpm - it was hot, to hot to hold in my hand for extended periods of time. It wasn't hot enough to melt anything I don't believe, but it was certainly not cool.
.75rpm - it was hotter than the 2.5. I image if you held it in your hand for more than a few seconds it might actually burn you. This was also my first extended run of this motor. It was loud, really loud. You could hear something turning in it constantly producting a racket. It was loud enough I've decide I won't be using this motor at all.

Hmm, I thought that the resistance might be the reason for the heat, and was going to run it on its own, but your test shows that they seem to be hot no matter what. I wonder if there is something about these motors we dont know...an extra control part, or that they arent supposed to be on 24/7...??? Im going to call Hansen on monday.

It's probable that these motors weren't meant to run continously. Short and intermittent use at best, like windshield wipers.
If the overheating of the motors is a problem, I may just run the swirler only when the lights are on(8hrs/day), powerhead on/swirler off. Hopefully, the motor can handle this.
If I'm successful with this project, I wanna make one for a sump return ala Seaswirl instead of a powerhead. How hot does a SeaSwirl run?
Just keeping this thread on top and padding my post total. After almost 5yrs, I still can't have a avater. I want to have my own nose-picking-child-avatar someday. Well, not exactly.

Well, these motors are cheap enough, and seem to heat up fast enough, that just looking for another motor might be a better idea. I have a DC motor already that I can use a power brick on to adapt to AC...

Im thinking about calling Paul at oceansmostions and simply asking for his motors...lol.

I found that the shroud that covers the flywheel popped right off on mine.
Tom, sure, you and I can talk. Why not at Bills? I will be bringing some streams and other DIY things to show.

Ok, I have the video up now..

It seems a little dark, but I think you can get a good feeling of the time it takes to make a pass in this.
Anyone know what temp pvc is good till? I ran my box 8 hrs solid and felt no heat on the bottom of the box where the motor is. I don't think it produces enough heat to do any damage.
The 2.5rpm motor says "Use for displays, timers, remote control, rotisseries.". If it can run that list I don't think we are going to have a problem. I felt like my motor reached a max temp, I didn't notice a difference between 30m on and 8 hrs on. But I do still want to get my dc motor version going, but dc motors get hot too.

Hmott, The video is awesome. Thats the exact range of motion I'm looking for. Are you using the same cam as the previous pics? Could you possibly take a close up? I'm having some serious cam issues on mine.
thanks,
