ELECTROMAGNETIC MOTOR WITH HORIZONTAL TRACTIVE CHARACTERISTIC Russian patent published in 1997 - IPC

FIELD: electromechanical devices with translational displacement of working section, such as those used for driving metering pumps. SUBSTANCE: motor has cylindrical field structure built up of frame 1 and core 2, as well as their joining flange 3, winding 4 placed on core 2, and flat external forward-displacement armature with ferromagnetic shunt in the form of ring 6. Side surfaces of ring 6 are of truncated cone shape. Inclination angle of external side surface 8 of ring 6 to frame 1 is greater then angle of inclination of internal side surface 7 of ring 6 to core 2. EFFECT: improved design. 5 cl, 4 dwg
