Abstract
A turbomachine having a rotor assembly, a stator assembly and a toroidal inductor. The rotor assembly includes an impeller. The inductor is located between the impeller and the stator assembly, and is exposed to an airflow generated by or acting upon the impeller.
Claims16
A turbomachine comprising:
- a housing,
- a rotor assembly comprising:
- an impeller being rotatable relative to the housing,
- a shroud being rotatable together with the impeller and covering the impeller, and the shroud being disposed between the impeller and the housing, and
- a toroidal inductor that directly encircles an outer surface of an inlet of the shroud and a portion of the impeller such that the outer surface of the inlet of the shroud and the portion of the impeller are longitudinally aligned with the toroidal inductor.
