ELECTRIC MACHINE (VERSIONS) Russian patent published in 2010 - IPC H02K21/00 H02K1/06 

FIELD: electricity.

SUBSTANCE: electric machine includes circular row of magnetic poles (1) and circular row of electromagnets (3) the magnet conducting elements (4) of which have central pole part (18) and two side pole parts (19, 20) related to it and placed from opposite laying sides of central pole part in the direction actually perpendicular to rotation axis. Winding (5) is arranged on central pole part (18). Part of winding 5 located between pole parts of magnet conducting element is more, as to length, than the half length of the whole winding. Central pole part (18) can be provided at least with one groove. Distance between centres of neighbouring pole surfaces is preset so that the angle value between pole surfaces can be within 0.7 of the angle value between magnetic poles to 1.3 of the angle value between magnetic poles. Angular size value of pole surface of side pole part has been set depending on angular size of pole surface of central pole part and has been chosen from the range of 0.55 of angular size of pole surface of central pole part to 0.95 of angular size of pole surface of central pole part.

EFFECT: improving technical characteristics by increasing the value of torque moment and power of electric machine at simultaneous decrease of mass and losses in its windings.
