LINEAR ELECTROMAGNETIC MOTOR Russian patent published in 1997 - IPC

FIELD: electromagnetic presses, hammers, and miscellaneous pulse-operated devices with translational-movement working elements. SUBSTANCE: motor has stator 1 accommodating coil 2 and armature 3 built up of cylindrical part 4 and disk part 5, guide frame 6 abutting against stator, slide bearings 7,8, reset spring 9, and adjusting shim 10. To increase specific energy of impact due to holding armature 3 during its initial stage of movement, ferromagnetic guide frame 6 has smaller cross-sectional area than stator 1 and is mounted for engaging external disk part of armature 3. EFFECT: improved specific energy of impact. 1 dwg
