Abstract: A contaminant-resistant motor may include an endbell with hermetic sealing of control components within a control module cavity in the endbell. The endbell configuration includes a front wall that isolates the control module cavity from contaminant-prone area of the motor assembly. The stator leads may be sealed within the lead passages using glass or other seals to further isolate the stator leads and control module cavity against ingress of contaminating liquids from the motor interior. The endbell configuration permits larger bearing elements to be used. A method of assembly of the motor may involve first fixture to align the stator, housing and REB to ensure concentric alignment of the stator to housing and the REB to the housing and a second fixture to isolate front and rear bearing bores and the stator inner diameter from encapsulation material and permit the stator to be molded to the housing.

The graded interlayer provides a transition in lattice constant from the third solar subcell to the fourth solar subcell. A lower fifth solar subcell is adjacent to the fourth solar subcell.
