摘要： 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.

摘要： A vacuum cleaner that includes a first dirt-separation stage, a second dirt-separation stage, and a vacuum motor for moving air through the first dirt-separation stage and the second dirt-separation stage. The vacuum motor has a centrifugal impeller driven by an electric motor. The first dirt-separation stage is then located upstream of the impeller, the second dirt-separation stage is located downstream of the impeller, and the second dirt-separation stage has a plurality of cyclonic separators that are arranged around the vacuum motor.
