ELECTRIC MOTOR Russian patent published in 2013 - IPC H02K21/12 H02K1/27 H02K3/04 H02K1/12 

FIELD: electricity.

SUBSTANCE: electric motor contains a rotor with pole permanent magnets magnetised radially and number of poles more than two and a stator consisting of a magnet core in the form of a hollow cylinder and a symmetrical three-phase biplane single-layer winding at inner surface with minimum gaps required for stator assembly between lateral surfaces of working areas of the coils. Working areas of the coils are located along the electric motor axis; at that number of coils in a phase circuit is selected as equal to the number of pole permanent magnets of the rotor.

EFFECT: increasing specific electromagnetic torque of an electric motor by improvement of operating efficiency of its stator winding.
