Toze Posted February 22, 2010 Share Posted February 22, 2010 I've been following this thread for a while now and since i don't see any new developments i started to think in another solution and i saw this pump that could be easier to control "Resun Wave Maker 15000". It's ugly but looks easy to control. Toze Link to comment
evilc66 Posted February 23, 2010 Share Posted February 23, 2010 With the changes made to the new Koralia Evolution's, it's almost not worth persuing. It's still a fun project though for those with the pumps. Although, I'm not sure that the new pumps can be speed controlled through just a VFD. Link to comment
Toze Posted February 23, 2010 Share Posted February 23, 2010 And applying this to this pump? From the info I found in the web its a dc pump and the controller switches from 12, 18 and 24v. With a better controller this voltage changes could me made smoother and maybe this could be a poors man vortech. Toze Link to comment
evilc66 Posted February 23, 2010 Share Posted February 23, 2010 No. The controllable Koralias are AC pumps controlled by a pwm pulse on an AC carrier. If they were DC, this thread wouldn't exist. The new pumps are AC, but have a better starting mechanism that alows them to be used on standard wavemakers. Link to comment

But what do I know, I have a mechanical degree! Gordon Link to comment
evilc66 Posted March 6, 2010 Share Posted March 6, 2010 AC doesn't mean that it runs on 110v AC from the wall. AC can come in all sorts of voltage flovors just like DC. Link to comment

What else would you need?! Link to comment

I'm using a PIC16F886. I would like to try my luck on writing the code for this project. I'm not familar with atmel's chips. Jason Link to comment

Put them in the code (with "define byte" or something similar) and the use a look-up table mechanism to use them. Like in my code.... Fery Could you tell me a little about the algorithm? I'm using a PIC16F886. I would like to try my luck on writing the code for this project. I'm not familar with atmel's chips. Jason Aaaa.... there is not much algorithm there.... The hardware PWM channel is doing almost everything. The program only checks the inputs and when they are changed it reprograms the PWM channel to generate the waveform... Not too much to say about it! Link to comment

Although, I'm not sure that the new pumps can be speed controlled through just a VFD. Evil, I'm sorry to go digging in the thread graveyard but I'm wondering a bit about playing around with these pumps. Do you know how well these would do being run off of a relay? Going a bit further, could I potentially run them with a PWM driven FET? Thanks a bunch and sorry if this information has been covered elsewhere. I've asked this in a separate thread but I'm finding more information that seems to disprove some of my earlier ideas. Link to comment
jm82792 Posted July 28, 2010 Share Posted July 28, 2010 PWM is a fail and a relay will cause a lot of mechanical wear. If you look back there is a special microcontroller motor driver, you could build it from scratch since the dev kits are rather expensive then use the guys example code. Link to comment
d9hp Posted July 28, 2010 Share Posted July 28, 2010 I've read through the whole thread and I have a thorough understanding of how to drive the old Koralia motors (I'm an EE) but I would rather go with something simpler (I have tons of SSRs around and evolutions are cheaper than the controlllables). Evil made it seem as though the new pumps can withstand more mechanical abuse, as that's basically what rapid on/off patterns are. Thanks a bunch! Link to comment
evilc66 Posted July 28, 2010 Share Posted July 28, 2010 The new pumps were designed to be used with a wavemaker. There is still a small click on startup, but it's far less abusive than it was with the original Koralias. I think pwm will be a very bad idea with this setup. All it would do it chatter.
