Do close by electrical currents interfere with sensors?
It is possible that strong DC electrical currents can influence the accuracy of the orientation measurement of the MotionTracker as a DC current generates a (static) magnetic field. In practice currents below 1 A does not influence the MotionTracker greatly if the distance between the wires and the MT is more than a few centimeters. If this is a problem in your application, consider using twisted-pair wires that will partically eliminate any radiated field.
