Lol, I haven't given up on the pump yet. I love the pumps. I love the original controller. But poor cooling, fan and bearing designs on the controller resulted in burnt out controllers.
I really want to know what the heck the difference is in the gen1 controllers and any of the next gens. I still have a brand new controller (gen1) and it easily pushes probably 1000 gph at 12' of head. Switch to the other controller...less than 2-300 gph. It's completely gutless. I've had one of the guys from Waveline tell me maybe the magnet has de-magnetized, they sent me new impellers. For some reason no one over there believes me that it is 100% the controller.

My plan is to use an integrated H bridge from ST.
It's the only simple alternative that supports 30A continuous duty at 600V for a sensor less BLDC application. The motor might be rated at 170W and 24V... with a bit of quick math 170/24=7.03A is actual draw. Now to actually further get into engineering we still don't know whatever its a Wye or Delta configuration of the windings inside the motor.
