  • Method and system for powering and measuring positions of a plurality of DC-motors over a wire interface
    Patent number: 8963473
    Abstract: A system comprising a motor controller for providing a plurality of first power signals and a single common second power signal to a motor module comprising a plurality of potentiometers connectable to a plurality of DC-motors. The power signals and feedback signals are sent over a wire interface having less than three wires per motor. A position feedback signal is read when a motor is being powered. The power signals may be DC-signals, pulsed or tri-state signals. The circuit may have a voltage divider consisting of two or three resistors. The actual motor position can be derived from the position feedback signals using one of two formulas or curves. A motor controller, and a method for driving a plurality of DC-motors is also disclosed.
