摘要： A rotor assembly includes a plurality of segmented magnets on an outer surface of a rotor core, a metallic layer on the outer surface of the plurality of segmented magnets, and a plurality of segmented metallic bands on the outer surface of the metallic layer. The plurality of segmented metallic bands is configured to secure the plurality of segmented magnets to the outer surface of the rotor core, and each band of the plurality of metallic bands has an axial length less than an axial length of the rotor.

摘要： An electric starter-generator is described. The generator may comprise a rotor, a housing, two bearings, a stator, and a cooling-fluid flowpath. The cooling-fluid flowpath may comprise a cooling-fluid entrance and exit, and a cooling-fluid channel in fluid communication with the entrance and exit. At least a portion of the channel may be defined by a fluid-tight coupling of the housing and a sleeve radially surrounding the outer race of either the bearings. The portion may form an annulus about the axis. The portion may comprise a radially inner surface defined by the sleeve, a radially outer surface define by said housing, and two axial surfaces. The two axial surfaces may extend a distance from the radially inner to outer surfaces that is less than a distance from one of the two axial surfaces to the other of the two axial surfaces.
