Abstract: An electromagnetic shield for an AC motor comprises a stack including a plurality of ferro-magnetic shield layers. Each one of the plurality of shield layers is at least partially electrically insulated from and substantially aligned with the others of the plurality of shield layers. The plurality of shield layers are positioned over a portion of the AC motor near an area where an axle will be positioned.

Abstract: An electric motor assembly. An air-ventilated electric motor includes a motor housing having a cooling-air inlet and a cooling-air outlet. An outlet muffler array is located outside, and spaced apart from, the motor housing and includes two or more outlet mufflers each having a fluid entrance and a fluid exit. An outlet connecting duct has a first end connected to the cooling-air outlet of the motor housing and has a second end connected in parallel to the fluid entrances of each of the outlet mufflers. The assembly may also include an inlet muffler array and an inlet connecting duct.

Abstract: A cryostat comprising an outer closed cylindrical vacuum vessel and a helium vessel is situated inside the vacuum vessel. The helium vessel has on its outside surface four radially extending trunnions situated on a horizontal plane passing through the center of the helium vessel. The trunnions are symmetrically spaced on either side of the helium vessel, about the helium vessel's axial midplane. Four straps have one end of each of the strap looping about a respective one of the four trunnions. The other end of each of the straps is rotatably secured to the circular end faces of the vacuum vessel, with the two straps from the trunnions closest to an end face secured to that end face.
