Copper Solar Fountain
I have a “Solar Copper Cascade” water fountain and I would like to know exactly how the magnetic coupling work
The sealed solar powered motor drives a pump impeller using a magnetic coupling. I don’t know if the impeller is supposed to be magnetized or not. Mine is and it doesn’t work most of the time. Maybe a spinning magnet in the motor is supposed to drive a non-magnetized impeller in the pump. I would like to know if this is how it is supposed to work.
Because the fountain is solar powered, the pumps are a brushless DC motor attached to an impeller. Brushless motors work by putting permanent magnets on the rotor. A small controller chip and power transistors sealed in the main body then drive the electromagnets of the stator all sealed inside the main motor body. The controller chip creates a rotating magnetic field in the stator that in turn causes the rotor to spin. The motor may be failing because the rotor is not properly aligned and is binding. Check that the rotor can freely spin inside the motor housing and doesn’t hit the side.
