Our pool pumps are typically 120 or 240V AC Motors - I'm wondering if anyone's familar with DC Motors to run pool pumps?

A contact to call or email so I can buy one would be amazing, or even a website - I already have the control electronics to manage the speed controll of a HVDC Motor - I need source of the motor itself, especially motors that are known to work in a pool/spa environment
 
You know, I just remembered that most motors in consumer grade treadmills are ~1HP DC motors and it's pretty easy to speed control a brushed DC motor compared to an AC motor that requires a VFD

You might ask why our pool pumps doesn't use brushed DC motors and I am guessing that's because the brushes require periodic scheduled replacement as they are a wear item - an AC motor is a brushless motor and it's the VFD that dies before the AC motor does

I wonder if anyone has tried to retrofit treadmill DC motors to their pool pumps!
 
Hello! I am curious about this question as well. I have a grid connected Solar system, but I would like to know if anyone has a mini off grid solar system just for their pool equipment. DC equipment with its own (off grid) panels would allow direct powering (during solar sufficient hours) without an inverter. Maybe with a small battery backup it would compensate for non solar hours too.

Try these guys. They have complete solar pump systems, DC pumps, DC pool motors.
