ELECTROMAGNETIC MOTOR (VARIANTS) Russian patent published in 2004 - IPC

FIELD: electrical engineering, namely electromagnetic motors with reciprocation motion of actuating organ, possibly used in drives of metering pumps, presses and other mechanisms.

SUBSTANCE: electromagnetic motor including cylindrical magnetic circuit having body, core and flange joining them, winding arranged around core; mounted on shaft flat outer straight-stroke ferromagnetic armature with shunt in the form of ring. According to first variant of invention armature has additional ring arranged at outer side relative to shunt. In body at side of armature there is turning corresponding to configuration of additional ring. In other variant additional ring is placed on armature between shunt and shaft of armature; core has turning corresponding to configuration of additional ring. According to third variant armature supports outer and inner additional rings. Outer additional ring is arranged on armature at outer side relative to shunt; inner additional ring is placed between shunt and shaft of armature. In body at side of armature there is turning corresponding to configuration of outer ring. Core also has turning corresponding to configuration of inner ring.

EFFECT: enhanced efficiency, possibility for achieving increased thrust effort at the same mass and size of motor.
