Not sure what is trying to be accomplished with the use of a speed controller. A controller only slows motor max. rpm's by decreasing the DC voltage. It can never increase rpm's since it can't increase DC voltage. So a 12v motor run on 6v the rpm's will already be 1/2 speed. Why would anyone want to slow it more?
