Its has a magnetic rotor that will spin when switched on, this rotor is connected to a propeller that pushes the water. I need something that can reduce the frequency of the AC supply so that the propeller will spin at a lower rpm. The best solution would be something like a rheostat where I...
Hi,
I have a submerged magnetic water pump that is pushing too much water at 8500L/hr. I know that the propeller rpm depends on the frequency of the AC supply but how can I build a simple circuit to reduce the frequency?
Thanks :smile:
