ELECTROMAGNETIC LINE MOTOR Russian patent published in 2000 - IPC

FIELD: line electric drives of electromagnetic actuators. SUBSTANCE: proposed electromagnetic line motor has electromagnet in the form of housing of cylindrical magnetic circuit, excitation windings, armature, driven link, compression springs, guides with rests and stopping members. Armature comes in the form of two ferromagnetic hollow semi-cylinders concentrically placed with clearance in axial hole of magnetic circuit on one of its sides facing one another with surfaces obtained as result of axial cut of hollow cylinder along generating line and attached to magnetic circuit in its middle part with internal butts with the aid of compression springs. Driven link is manufactured in the form of nonmagnetic plate placed freely in axial hole of magnetic circuit between above-mentioned surfaces of semi-cylinders forming armature and having stopping members on side faces which contact rests of guides. EFFECT: simplified design and reduced energy consumption. 3 dwg
