Abstract
Power conversion device including: a first fluid conduit; a diffuser attached thereto with at least one vane supporting a diffuser hub; a rotor supported by the diffuser hub and having a rotor blade, hub, and shroud at the periphery thereof with at least one magnet thereon; a housing surrounding the shroud and attached to the diffuser, and having a stator including laminations forming poles and at least one coil therearound, the stator encapsulated in a non-metallic compound to prevent fluid contact with laminations and coil(s); a commutation control connected to the coil(s) and having external leads; and a second fluid conduit attached to the housing so fluid flow causes a torque load on the blades, rotating the rotor and inducing a magnetic field in the poles to generate current in the coil, converting hydraulic power to electric power. The device operates as a turbine/generator and as a motor/pump.
