Abstract: An electrical coil assembly for use in a flooded electrical machine operating in an electrically conductive and/or chemically aggressive medium, and a method for manufacturing an electrical coil assembly, are disclosed. The electrical coil assembly incorporates an electrical cable coil winding and a magnetic core. The electrical coil winding is wound of electrical cable with dielectric insulation that is also a waterproof molecular barrier and is covered with at least one layer of waterproof adhesive material. The magnetic core is substantially surrounded with a dielectric insulation layer, which is covered with at least one layer of waterproof adhesive material. The combination of dielectric insulation and waterproof adhesive layers provide protection against the ingress of water and accordingly reduce risk of electrical fault and failure of the electrical coil assembly in submerged service.

Abstract: An apparatus is disclosed for a hybrid electric power system for use in a multi-wheeled hybrid electric vehicle, and particularly for use in hybrid electric vehicles designed for operation in hostile environments where reliability and survivability of the propulsion system of the vehicle are important. The hybrid electric power system advantageously comprises at least one segmented electrical machine having multiple pairs of parallel stator segments with a magnetic rotor segment between each pair, for generating power from a thermodynamic engine, or for providing power to a driven wheel of the hybrid electric vehicle. A hybrid electric power system is also provided which comprises at least one distributed segmented electrical machine which comprises a distributed electrical energy storage system.

Abstract: A generator or motor apparatus having a stator formed of a plurality of pairs of parallel stator segments is provided The pairs of parallel segments are connected together to form a channel in which an annular rotor moves The annular rotor also comprises a plurality of detachable segments connected together to form an annular tram operable to move through said channel Each stator segment comprises a stator winding set and each rotor segment comprises a magnet dimensioned to fit between the parallel spaced apart stator segments The apparatus may include a support structure, the rotor segments being slidably coupled to the support structure and the stator segments being attached the support structure The apparatus may be a rim generator, wind turbine generator or other electrical machine The stator winding set includes a winding, and may include other electrical or electronic components, including possibly a power factor capacitor, direct current filtering capacitor, supercapacitor, and one or more diodes The s

Abstract: A flow enhancement improvement for an underwater turbine generator (10) is disclosed wherein a longitudinal hole (240) is disposed in the central area (26), typically a hub (20) of the generator (10), and a second, augmentor duct (41), preferably rigid, is disposed about the outer duct (40) or housing of the unit to create a slot (200) area The slot (200) and hollow hub (20) create areas of smooth, laminar fluid flow. The leading edges of the hub (20) or central ring and the augmentor (41) and outer ducts (40) are elliptical to enhance the fluid dynamics of the structure.
