Propulsion System for a Vehicle

摘要

A propulsion system for a vehicle includes a supporting structure and a plurality of propellers carried by the supporting structure. Each propeller is associated to an electric motor with a toroid geometry, having an annular rotor rotatable within an annular stator and defining therewithin a central aperture. The blades of the propeller, which are carried by the rotor, extend to the central aperture.

1. A propulsion system comprising:
a supporting structure; one or more electric motors supported by the support structure and having a toroid configuration, each of the one or more electric motors having an annular stator and an annular rotor rotatable within the annular stator, the annular rotor of each of the one or more electric motors encircling a central aperture; one or more propellers with each of the one or more propellers being separately engaged with a corresponding one of the one or more electric motors, each of the one or more propellers having a central axis and one or more radial blades that are carried by the annular rotor of the corresponding one of the one or more electric motors and extend into the central aperture thereof, each of the one or more radial blades starting from a wall of the annular rotor and ending at a blade free end which is located at a distance from the central axis; wherein the annular rotor and the annular stator of each of the one or more electric motors forms a guide tube through which an airflow passes when the one or more electric motors are activated, and wherein the airflow through the guide tube of each of the one or more electric motors converges towards a focusing area.
