Combination Tire and Cable Drive Motor
For Music Man, I had to make a drive motor capable of driving three fully loaded revolves for under $100. The 3/4 horse motor and VFD were pulled from an old AC unit the school no longer needed. The tire and belts came from the bus barn and all the unistrut and threaded rod came from past shows. I only had to buy a few cables and pulleys. I geared it down to about 30 RPM on the tire and was able later to drive a twenty foot, two ton revolve for Christmas Carol. The control pickle was able to start, stop, set clockwise or counter-clockwise, and had an Estop. Later, I wired it with limit switches that would flip to automatically stop it at the appropriate time.
