Patent ID: 7032859

Claim:
An aerial vehicle for air transportation comprising: (a) a vehicle body; (b) a cylindrical shaped ducted housing centrally located within said vehicle body, said cylindrical shaped ducted housing including: (i) first and second stators, said first stator being positioned in an upper portion of said ducted housing, and said second stator being positioned in a lower portion of said ducted housing; (ii) said first and second stators having a stator core and a plurality of excitation windings; (iii) said stator core for said first and second stators having a core portion and a stator salient pole portion, said core portion forming a magnetic circuit to generate a magnetic flux and then pass said magnetic flux to the stator salient pole portion of said stator core; and (iv) said first and second stators having said plurality of excitation windings wound round said stator salient pole portion for said first and second stators in a uniform and concentrated manner; (c) first and second counter rotating propellers rotatably mounted within said cylindrical shaped ducted housing, said first counter rotating propellers being positioned within the upper portion of said cylindrical shaped ducted housing, and said second counter rotating propellers being positioned within the lower portion of said cylindrical shaped ducted housing, said first and second counter rotating propellers being operative to provide vertical takeoff and landing and translational flight capabilities for said aerial vehicle; (d) said first and second counter rotating propellers having a plurality of equally spaced apart blades, each of said plurality of blades having a permanent magnet located at a tip of said blade; and (e) an electromagnetic drive controller connected to the plurality of excitation windings of said first and second counter rotating propellers, said electromagnetic drive controller providing electrical current to the excitation windings of said first and second counter rotating propellers to generate said magnetic flux, said magnetic flux passing through the permanent magnets for said first and second counter rotating propellers generating torque which when applied to the blades for each of said counter rotating propellers causes the blades for each of said counter rotating propellers to rotate.
