ELECTRIC MOTOR Russian patent published in 2008 - IPC H02K19/24 H02K29/06 H02K37/10 

FIELD: electric engineering, namely - electric motors (synchronous ones, with valve control, stepping ones) meant for driving electrical actuating mechanisms and devices.

SUBSTANCE: the electric motor contains toothed magnetic-soft rotor and stator, made in form of magnetic conductor with poles, segments and tangentially magnetized constant magnets, on the poles coils are positioned belonging to m-phased stator winding, to each segment, constant magnets of same polarity are adjacent, number of segments and poles is divisible by 2m, teeth on segments and the rotor are made in even steps, axes of teeth of adjacent segments are shifted for 360/2m electric degrees angle, windings of each phase are made of serially connected coils positioned on poles, with distance of m-1 pole between them, segments and tangentially magnetized magnets are positioned between stator poles and rotor. Non-magnetic gaps between poles and segments are of sizes comparable to the length of air gap between toothed surfaces of aforementioned segments and rotor.

EFFECT: improved power characteristics, expanded functional capabilities of electric motor.
