Abstract: A variable speed electric motor controller includes a rotating cylinder having a variable amount of conductor material and a variable amount of insulator material along its length such that one side is mostly insulator and the other side is mostly conductor. An electrical connection, such as a brush, can contact the rotating cylinder and be moved therealong. A stationary electrical connector/brush can be permanently electrically connected to the conductor material. The flow of electricity from the movable brush to the stationary brush can be controlled by the speed of rotation of the shaft and the position of the movable brush therealong. The output can provide variable power to a load, such as an electric motor.
