Abrégé

Power conversion device (20) including: a first fluid conduit (21); a diffuser (22) attached thereto with at least one vane supporting a diffuser hub (25); a rotor (23) supported by the diffuser hub and having a rotor blade (23 A), hub, and shroud (28) at the periphery thereof with at least one magnet (29) thereon; a housing (32) surrounding the shroud and attached to the diffuser, and having a stator (36) including laminations (31) forming poles (3 IP) and at least one coil (33) therearound, the stator encapsulated in a non-metallic compound (35) to prevent fluid contact with laminations and coil(s); a commutation control (44) connected to the coil(s) and having external leads (45); and a second fluid conduit (24) 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.
