Abstract
A motor includes a stator and a rotor coupled via the center hub of the rotor. The stator includes a support ring, the support ring comprising a plurality of windings arranged circumferentially. The rotor is configured to operate as a rotating propeller and includes a center hub, a rotor support ring, and a plurality of blades. The rotor support ring comprises a plurality of magnetic poles arranged circumferentially. Each particular blade is individually coupled to the rotor support ring.
