Any DC motor experts out there?

Not an expert, but it's pretty amazing how you can apply a little more to a DC motor and they'll still work fine. Go overboard and you'll be buying a new one though.

My biggest interest in this pump is the ability to produce a wavebox out of it. I'm pretty certain I could build a timer/controller, which is the main issue with AC pumps.

I'm with everyone else, I wish these would come into the states, and even better, be sold by pump only.

How much is a little more? 10%? 20%?. Will 50% be overboard? If a DC motor is rated say 20V and 2A max, and you stay within the 2A, is this fine?

I assumed a controllable DC motor is much more complex than an AC motor, with electronics in it that may be less capable of withstanding overload.

If I had to take a guess, I'd say 50% more is too much. A safe guess even.

Depends on the motor and the amount they're using it at currently. I've taken small DC motors and put ridiculous amounts of current and voltage through them, just playing around. As long as it's not done for too long of a time, you'd be surprised what they can take. I'm not saying you wouldn't be wearing them down quicker either though....

If we had a data sheet on the motor used, I'd imagine we'd be able to draw better conclusions. I'm not sure you could do much to tell what these motors could take without testing them.

If these pumps were stateside, I'd purchase a few of them to play around with. Especially if we could purchase the pump without the controller.

Thank you for the response. Let me be more specific, and I know this is a little off but bear with me.

The Tunze 6055s will soon be available. Based on the information we know so far, the transformer is rated 800mA on the AC side, and 12-24V/1.2A on the DC side, the pump motor is rated 12-24V and Imax at 1.2A as well, but Tunze rated the pump at 18W only.

Given the above, can we safely over drive the motor to 28W even though the pump is rated at 18W? The transformer has several speed settings marked by 12V, 14V...24V.

When I say safely, I really mean long term safe operation.

I honestly wouldn't know. I wish I could give you more help, but I'm simply not knowledgable enough in motors to give what I believe to be an accurate assumption.

 

[jacmyoung]

I didn't think there could be an easy answer, the only sure way to find out may be just as you said to test it and see how long it will last.

Resun Motor is on-and-off periodically by PIC controller. It produces some waves.

That cool. What's a PIC controller?

Wow, that's some nice pulsing action. Any more info on how that was done?

The pic controls the DC motor. It's like any other controller, with some basic C or assembly language skills, you can have that pic control when the motor turns on or off. Shouldn't be too hard to control voltage either.

 

[HippieSmell]

Hmmm, I took a course in C++. I was horrible at it, but maybe I can do this. Where might I find this PIC? Are they expensive?

I think we can use 2 transformers, 12v and 24v, wire them parallel and to the pump. Plug both into Chauvet timer, select 2 channel and fast chase 1 sec. to 1 min, adjust the duration. Chauvet will switch between 24v and 12v and the pump will continuously run at 24v and 12v without stopping at all, great for for wave box. This is easiest way, imo.

[jacmyoung]

A great find, but isn't this the same as the powerstrip type wavemakers? Also will the fast on and off shorten the life of the transformers? I know the pump is on all the time so it should be ok.

Also will it be harmful connnecting two transformers in parrallel, one is live one is not, back and forth?

I know these are rated at aroung 4000gph on the top end. These put out more than 2 Hydor Koralia 4s for sure. I had two 4s on the left and this on the right and it pushed the water column pretty far towards the 4s basically meaning two 4s couldn't beat push it back on the high end. I think 3 might tie it as I added a Tunze 6045 and the flow started to even out in the middle of my tank, but was still being pushed towards the 3 pumps.

I also hacked the controller off and wired the brick directly to the pump. Oddly the transformer kicks zero volts out. It must need a specific load before it will push full voltage out... probably a safety feature. The transformer still will power the controller and the pump when wired back up. On my bench, I reved the pump up to 24v and it was pulling about 1300ma. Unfortunately I don't have a power supply that kicks out 24v at 1500ma that I can use to get this in my tank for long term testing. I plan on ordering one for $10 and see how long the pump will run full out. I did try it out at 12v with a PC power supply in a test tank I have and the pump fired right up but obviously at around half power.

Hope this helps... this pump has great potential and while it is big they did three things very right IMO. First, it is DC which means no worrying about prop running backwards if it is wired properly and it can be slowed down easily. Second, the pump is wide rather than tall. It has a reasonably slim profile as it is wider than tall. Lastly, the pump doesn't have any slots for intake water at the top which allows the pump to be closer to the surface without a vortech and sucking air into the pump. Nice if it were on a magnetic base, but you can pick up some strong acrylic coated magnets for 10-15 bucks.

Where can you get those magnets, I have one I would love to mount differently.

For waveboxes you often need to set the timing to less than one second (depending on the size/shape of tank, position of wavebox). Furthermore, you need to have fine tunning ability for the timing - certainly within a tenth of a second, or better. I believe Melev's Reef has a diy timer that he rigged for a Tunze to make a wavebox. I'm sure it should work for this. It seems a little less hairy than the Chauvet method IMO.

 

[L98-Z]

Tenths of a second aren't hard with a microcontroller. I'm pretty certain I could figure it out. The problem is I don't want to buy their controller and pump, only to get the pump. It's a waste of money.

 

[aninjaatemyshoe]

I was wrong about the source. Here is the link to the schematics for the controller used:

Of course, this design would have to be modified to fit the Resun, but I think it gives the basic idea for those who are good with circuits (which I am not).
