ELECTRIC PROPULSION FOR CONVERTING ELECTRIC ENERGY INTO LINEAR TRACTION FORCE Russian patent published in 2009 - IPC H02K7/06 H02K57/00 

FIELD: electricity.

SUBSTANCE: electric propulsion consists of housing, stator and rotor with movable poles being inertial masses. Rotor poles consist of core and winding. Traction force is created with unbalanced centrifugal forces appearing at non-uniform movement of movable rotor poles installed individually along closed convex curve and interacting with magnetic field of stator. Stator has the number of pole pairs, which is equal to that of rotor, which create non-uniform magnetic field. Non-uniformity of stator magnetic field is created with different linear sizes and various number of loops of stator poles winding. The more the pole is, the more intensive magnetic field it creates in its section. Poles are located along the stator perimetre with gradual decrease of their size, from maximum pole to minimum one at diametrically opposite points of the perimetre.

EFFECT: simplifying electric propulsion design and decreasing material consumption.
