Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A motor control system for controlling a plurality of DC-motors, the motor control system comprising: a motor controller, configured for providing a number of first power signals each for being applied to one of the DC motors and a single common second power signal for powering the plurality of DC-motors, and configured for receiving a plurality of position feedback signals from the plurality of DC-motors; one or more motor modules connectable to the…
