Abstract: A method of mounting a rotor assembly to a frame of an electric motor includes providing a rotor assembly having a bearing and a frame having a bearing seat. The method includes locating the bearing within the bearing seat, applying a first adhesive at a substantially hidden interface between the bearing and the bearing seat, applying a second adhesive at a substantially visible interface between the bearing and the bearing seat, and curing the first and second adhesives using different curing processes.

Abstract: A compressor has a rotor assembly having an impeller for generating an airflow through the compressor, a stator core assembly for causing rotation of the impeller, and a diffuser assembly for acting on the airflow generated by the impeller. The diffuser assembly has a first diffuser stage and a second diffuser stage. The first and second diffuser stages are separate components connected to one another by a fastener.

Abstract: A brushless motor has a rotor assembly including a shaft, an impeller, a bearing assembly and a rotor core. The brushless motor has a stator assembly and a frame having an outer portion and an inner portion radially inward of the outer portion. The inner portion supports at least one of the rotor assembly and the stator assembly. The brushless motor has a strut extending between the outer portion and the inner portion. The strut extends at least partially into a recess formed in the stator assembly.
