ERECTION TORQUE MOTOR Russian patent published in 2012 - IPC H02K26/00 

FIELD: electricity.

SUBSTANCE: erection torque motor comprised a magnetic system that consists of a multipolar permanent magnet and a magnetic conductor, and also an active element in the form of a spirally wound electroconductive tape coated with a layer of insulation material. At the side edges of the tape there are narrow transverse cuts arranged in turns at both edges. These cuts at each turn of the tape winding are above and under similar cuts on underlying and overlying layers. These cuts create side slots on a wound active element, besides, the distance between adjacent slots corresponds to a pole division of the magnet. A DC source is connected to ends of the wound tape.

EFFECT: expansion of the working range of erection torque motor rotor and stator mutual rotation angles.
