Abstract: A monolithic heater body includes a combustor body and an eductor body. The combustor body has an annulus with an outward annular wall and an inward annular wall. The annulus defines a conditioning conduit between the outward annular wall and the inward annular wall, and a combustion chamber circumferentially surrounded by the inward annular wall. A distal portion of the conditioning conduit fluidly communicates with a distal portion of the combustion chamber. The eductor body defines a plurality of eductive pathway couplets circumferentially spaced about a perimeter of the annulus. Respective ones of the eductive pathway couplets have a motive pathway and an eduction pathway respectively oriented oblique to the annulus and fluidly communicating with the conditioning conduit. Respective ones of the plurality of motive pathways are configured to provide a jet of intake air from a corresponding plurality of intake air pathways to the conditioning conduit.

Abstract: An electric pump powered by an electric motor having a stator disposed within a hollow rotor is provided. Impellers on the rotor outer surface extend into a fluid flow path defined by the pump. One or more torque-producing rotor sections are driven by a plurality of independently controllable stator sections disposed within the rotor cavity. The relative positions of the rotor and stator are maintained by a plurality of bearings configured to allow rotation of the rotor and defining a bearing span. The pump is configured such that the stator and rotor share the same bearing span. Such an arrangement reduces motor windage losses relative to conventional motors in which the rotor is disposed within the stator, owing to a reduction in the diameter of the air gap between the stator and the rotor. In addition, the peripheral speed of the pump is increased owing to an increase in the rotor diameter.

Abstract: An assembly includes multiple adjoined rotor sections each having multiple poles and multiple void rows therethrough that are radially distributed in each of the poles. The rotor sections are skewed in a circumferential direction. The assembly also has multiple conductive rings that substantially surround one of the void rows. A method of assembly and electric machines and vehicles using the assembly are also disclosed. Aspects reduce torque ripple in electric machines and allow for encoderless/sensorless operation in an electric machine using the rotor assembly. The present invention has been described in terms of specific embodiment(s), and it is recognized that equivalents, alternatives, and modifications, aside from those expressly stated, are possible and within the scope of the appending claims.

Abstract: An active magnetic bearing system includes a radial actuator and an axial actuator. The radial actuator includes a radial stator coupled to a stationary component, and a radial rotor coupled to a rotatable impeller. The radial rotor extends circumferentially with respect to the radial stator and is configured to rotate about the radial stator. The axial actuator has first and second rotor rings and first and second stators. The first rotor ring is attached to a first axial end of the impeller, and the second rotor ring is attached to a second axial end of the impeller. The first and second stators are coupled to the shaft adjacent the first and second rotor rings, respectively. The radial actuator is positioned axially between the first and second rotor rings.
