A floor cleaning or burnishing machine has at least one motor controller that is electrically connected to an analog joystick control, right and left potentiometers, an electrical power source, and right and left electrical drive motors. The right motor is mechanically connected to a right rear steering drive wheel and the left motor is mechanically connected to a left rear steering drive wheel. Rotational speed and direction of each rear wheel is independently controlled, by way of the joystick in cooperation with respective potentiometers, in either a forward or reverse direction. At any given time, each potentiometer controls a respective motor controller which individually controls the rotational speed and direction of a respective wheel, thereby each wheel is capable of rotating in an opposite direction at a different speed to the other wheel. To slow the floor cleaning or burnishing machine down, regenerative braking is utilized by operating the motors as generators. |
