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： A rotor (12) of a turbomachine includes a rotor drum (64) located at a central axis (14) and a plurality of buckets (16) secured to the rotor drum (64). A rotor shell (38) extends between axially adjacent buckets of the plurality of buckets (16) and is secured to and supported by the plurality of buckets (16) defining a cooling passage (50) between the rotor drum (64) and the rotor shell (38). A low pressure sink (52) is located at an upstream end of the rotor (12) receptive of a coolant flow through the cooling passage (50). A method of cooling a rotor (12) of a steam turbine (10) includes locating a rotor shell (38) radially outboard of a rotor drum (64) defining a cooling passage (50) therebetween. A flow of steam (60) is urged from a downstream portion of the steam turbine (10) through the cooling passage (50) toward a low pressure sink (52) located at an upstream end of the steam turbine (10) thereby cooling the rotor (12).
