摘要： An electrical machine comprising a rotor is presented. The electrical machine includes the rotor disposed on a rotatable shaft and defining a plurality of radial protrusions extending from the shaft up to a periphery of the rotor. The radial protrusions having cavities define a fluid path. A stationary shaft is disposed concentrically within the rotatable shaft wherein an annular space is formed between the stationary and rotatable shaft. A plurality of magnetic segments is disposed on the radial protrusions and the fluid path from within the stationary shaft into the annular space and extending through the cavities within the radial protrusions.

摘要： Provided is an apparatus, for example, for use with a rotating electric machine, that includes a housing. The housing can include a housing main portion and a housing end portion. The housing main portion can be configured to be disposed proximal to a body portion of a stator section of an electric machine. The housing main portion can define a main fluid channel that is configured to conduct fluid therethrough. The housing end portion can receive fluid from said main fluid channel and direct fluid into contact with a winding end portion of a conductive winding of the stator section.

摘要： A rotor of a turbomachine includes a rotor drum located at a central axis and a plurality of buckets secured to the rotor drum. A rotor shell extends between axially adjacent buckets of the plurality of buckets and is secured to and supported by the plurality of buckets defining a cooling passage between the rotor drum and the rotor shell. A low pressure sink is located at an upstream end of the rotor receptive of a coolant flow through the cooling passage. A method of cooling a rotor of a steam turbine includes locating a rotor shell radially outboard of a rotor drum defining a cooling passage therebetween. A flow of steam is urged from a downstream portion of the steam turbine through the cooling passage toward a low pressure sink located at an upstream end of the steam turbine thereby cooling the rotor.
