I would like to PWM speed control a 24V 2A DC Brushless Pump using an Arduino for my nano-brewery project. I've been searching for a Speed controller on Amazon or Ebay. But, i either find brushed motor controller or three phase controllers. I have only 2 wires on pump. Any recommendations on what I need to purchase? Thank you.
I need to control 3 pumps.
