ELECTROMAGNET

摘要

FIELD: electrical engineering. SUBSTANCE: electromagnet includes body 1 carrying control coil 2, bearing flange 3 with immobile stop 4 having hole. Flow hole forming internal 7 and external 8 edges is made in internal flange collar. Outer surface of flange is its cover. Bearing flange 3 includes guiding bushing 13 made from antifriction material. Pull-in armature 9 has cylindrical surface with groove forming two steps 10, 11. Step 10 is close to internal edge 7 of internal flange collar and step 11 is close to external edge 8 when armature is initial position. Guiding bushing 13 of armature is located in hole of its end face. Guiding rod 14 is manufactured from nonmagnetic material and is positioned axially symmetric in bottom of cover 15 of flange 6. Rod has ferromagnetic distance sleeve 16 located in zone of its joint to armature 9 over section between end face of armature in its initial position and guiding bushing of stop. EFFECT: provision for traction characteristic maximally matched with mechanical characteristic of drive. 2 dwg
