ELECTROMAGNETIC MOTOR Russian patent published in 2006 - IPC H01F7/16 

FIELD: electromechanical devices with working link performing translational movement; dosing pump drives.

SUBSTANCE: proposed electromagnetic motor has cylindrical magnetic circuit with external plunger armature and stator incorporating winding, core, external wall, and flange that joins them together; winding is placed around cylindrical part of core so that its sectional area formed by plane crossing symmetry axis of motor is trapezium-shaped, trapezium bases being parallel to motor axis. At least one of trapezium internal angles equals α, where 45°<α<85°, and surface of armature drawn-in part facing the winding is tilted through angle β to motor symmetry axis, where 45°<β<85°. Outer side surface of core and inner side surface of external wall may be tilted to motor symmetry axis and drawn-in part of armature may be made in the form of ring with truncated-cone side surfaces.

EFFECT: enhanced economic efficiency of motor.
