Maxspect Gyre Icecap module contents?
Re: Maxspect Gyre Icecap module contents?
I forget who but someone said it was like an RC plane servo type interface and it had a different type of PWM input pattern. Lets see if I can pull up the thread

The Gyre pump (like most so called DC pumps) is really a 3 phase AC pump. The IceCap module accepts a 0-10Volt signal and outputs a 3 phase AC signal where the frequency, current and voltage of the AC are all modulated by the 0-10 Volt input.
It is not simply a matter of changing voltages, it is actually varying the frequency of the 3 phase AC signal going to the pump. Reversing is acomplished by changing the phase order of the 3 AC phases (just like in any 3 phase motor).
The 3 phase output is itself generated using PWM techniques, but it is PWM at 50 KHz and the PWM is being used to generate complex 3 phase AC waveforms.
By putting different rotors in the Gyre it can be configured to produce maximum flow forward, maximum flow backward or a balanced flow. In the balanced flow mode, one end of the pump moves a lot of water when the pump spins one way, the other end of the pump moves a lot of water when it spins the other way. The Gyre is shipped with 4 rotors. 2 A rotors and 2 B rotors. Normally you have an A and a B installed, which gives full output when going forward. If you were to reverse the 2, youwould get full output when going backwards. If you put in 2 A's or 2 B;s you get balanced flow, where it moves the same amout of water in either direction.
I have 2 Gyre 150s in my 6' long 180 gallon tank both running under Reef Angel control with the Ice Cap modules.. I run them in a reversing cycle where one is on at a time and the one that is on goes up to 40%. Twice a day I kick them up to 60% for 1 minute to flush stuff out of the rocks. At 100% the Gyre is so strong that the water will flow in a laminar sheet all the way across the top of the 6 foot length of the tank, down the far end, and stir up gravel on the bottom at the end 6 feet away from the pump.
I have 2 ecotech 40W pumps that are for sale if anyone wants them. After seeing the Gyre I see no use for them anymore. The Gyre is far more powerful, much quieter, and produces this cool laminar flow.

I am setting up a 180g as we speak and am planning to do exactly what you're saying with 2 XF150s on my ReefAngel. What orientation do you have them in? (I assume one on each end near the top horizontally from what you posted)
Re: Maxspect Gyre Icecap module contents?
Yes, I have them horizontally on each end a few inches down from the top. The only problem I have is that on one end, the gyre goes behind my overflow, so I moved that one as close to the front as possible.AlanM wrote: Don! Thanks for all the info about what the Gyre pumps do.
