REPULSION COMMUTATOR-FREE ELECTRIC MOTOR Russian patent published in 2011 - IPC H02K17/16 H02K17/02 

FIELD: electricity.

SUBSTANCE: in the proposed electric motor containing stator (2) with single-phase winding (6) and rotor (13) with squirrel cage (24), stator (2) has magnetic core (3) and magnetic core (4), the symmetry axes of which are parallel to each other and perpendicular to rotor (13) rotation axis; poles (5) of magnetic core (3) lie in its symmetry axis, magnetic core (4) is ring-shaped and has one pair of poles (11) on inner side of the ring; angle between symmetry axis of each pole (11) and symmetry axis of magnetic core (4) lies within 15° to 75°; on poles (11) there arranged is winding (12) in the form of coil wound on spiral; on the part of magnetic core (4), which is opposite to poles (11), there is winding (9) representing the coil wound on spiral; windings (9) and (12) are connected to each other so that the direction of their coiling is the same; rotor (13) is located between poles (5) and (11).

EFFECT: simplifying the design, improving operating reliability of electric motor, and reducing its operating costs.
