    Abstract: An electric motor includes a stator and rotor. The stator includes a stator core defining a stator bore, and a plurality of windings having end turns extending from the stator core. This includes a central region configured to be disposed in the stator bore, and first and second end regions extending from the central region and aligned with the end turns of the plurality of windings. The rotor defines a cooling bore in fluid communication with a low-pressure cooling fluid source and includes a plurality of cooling jets in fluid communication with the cooling bore and disposed in the first and second end regions. The plurality of cooling jets extends radially outward such that each cooling jet is configured to pull cooling fluid through the cooling bore and eject cooling fluid toward the end turns in response to centrifugal force caused by rotation of the rotor within the stator bore.

    Abstract: A rotating machine includes a shaft, a first impeller wheel, and a second impeller wheel. The rotating machine also includes a first seal assembly including a first carbon ring disposed about the shaft, with the first carbon ring having a first carbon surface. The first seal assembly also includes a first mating ring disposed about the shaft, with the first mating ring having a first mating surface facing and configured to contact the first carbon surface. The rotating machine additionally includes a second seal assembly including a second carbon ring disposed about the shaft, with the second carbon ring having a second carbon surface. The second seal assembly also includes a second mating ring disposed about the shaft, with the second mating ring having a second mating ring surface facing and configured to contact the second carbon surface.

    Abstract: A rotating machine includes a machine housing defining a housing interior, a shaft disposed in the housing interior, with the shaft having a length and an axis extending along the length. The shaft is rotatable about the axis. The rotating machine also includes an impeller wheel disposed in the housing interior and coupled to and rotatable by the shaft, with the impeller wheel having an angular position with respect to the axis. The rotating machine further includes a backplate coupled to the machine housing and having a first side facing the impeller wheel, at least one target element coupled to and rotatable with the impeller wheel, a circuit board coupled to the first side of the backplate and facing the impeller wheel, and at least one sensor disposed on the circuit board for detecting the at least one target element to determine the angular position of the impeller wheel.
