Abstract
An enhanced counter-rotating electric motor and an associate propulsion system for use with a water-vehicle includes a motor housing, a stator within the housing that rotates about a central axis in one direction, an armature within the stator that rotates about the central axis in an opposite direction from the stator, a first axle that is secured to the stator and extends out from the housing, a second axle that is secured to the armature and extends out from the housing, water-tight rotational seals about each of the two axles, a centrifugal-force-balancing electrical connection mechanism that supplies functioning electrical communication between the motor and external electrical circuitry while operating the motor, and a propeller secured to each said axle.
