摘要： A rotor assembly, for example for a high-speed synchronous machine, comprises a generally cylindrical rotor body mounted to rotate on an axix of rotation. Conductors of the rotor windings are mounted in axially extending slots on the rotor body and are retained in the slots by conductive slot wedges (38). The conductors emerge from the slots to extend at least partially circumferentially around opposed ends of the rotor body. At each of the opposed ends of the rotor body a chrome steel end bell (36) contacts the slot wedges (38) and circumscribes a portion of that end and the circumferentially extending conductors. A conductive ring (48) extends around the inner surface of the end bell (36) in contact with the end bell and the slot wedges but insulated from the conductors and at least a part (58) of the outer surface of each end bell is coated with a conductive coating material (52). The conductive materials have a lower electrical resistivity than that of the end bell and may be copper or silver. The conductive ring (48) carries low frequency rotor-induced currents and the conductive coating (52) carries high frequency stator-induced currents.

摘要： A propulsion unit arranged to propel a water borne vessel comprising an electric motor, arranged to provide propulsion, and a housing (4), arranged to contain the motor, the interior of the housing (4) being maintained at an increased pressure of above roughly 2 bar to increase the cooling effect of a cooling gas maintained therein. Further, it is disclosed that for the propulsion unit to comprise a housing (4) that contains the motor, wherein an end region of the housing is provided with a heat exchange mechanism (59) arranged to cool cooling gas passing thereover, the heat exchange mechanism being associated with the housing such that, in use, water surrounding the housing absorbs heat therefrom. The unit can be arranged to make use of either, or both, of the features.

摘要： A stator assembly (1) for an electrical rotating machine, such as a high-speed 2-pole motor or generator. The stator assembly comprises a plurality of generally annular laminated core sections (2) arranged along the axis of the machine. Spacer pins (16) are provided between adjacent sections, thereby defining, between each adjacent pair of sections, a radially and circumferentially extending coolant duct (14) enabling coolant to flow between the interior region (25) of the assembly and its exterior surface. A plurality of axially extending channel members (8) are circumferentially spaced apart on the exterior surface to convey pressurised coolant to the ducts (14). Along the length of the assembly (1), alternate first slot openings (22), covered by the channel members (8), and alternate second slot openings (24), extending circumferentially between the channel members, are obturated, but in staggered relationship to each other. This arrangement enables increased economy of manufacture and increased cooling efficiency.
