Anyone ever tried buying a ceiling fan from a big box store that says it has a DC motor and trying to run it on DC? I told my wife it was possible so she called my bluff, went to Lowe's and bought two. I reluctantly tore one apart and found that they have 3 wire brushless DC motors. I got on fleebay and found a DC motor driver that would run on our house's 24v DC setup. I temporarily hooked everything up to a car battery and it seems to work. The motor driver has a speed control and a forward/reverse option. I quit working on the project to do the garden while the weather is nice but with some rain in the forecast I am ready to get back on it.
