COMBINED ELECTRICALLY CONTROLLED DRIVE

摘要

A combined electro-controlled drive in which electric power is transformed to linear displacement of movable part of the drive has at least two electric coils and at least one armature, this has ferromagnetic part and electro-conductive non-ferromagnetic part and interacting with electric coils at connection of the last ones to source of electric energy at least one of which is pulse source of electric energy. At that the outer working surface of ferromagnetic part is placed in the area of effect of one coil and outer working surface of non-ferromagnetic part is placed in area of effect of the other coil and at least one of electric coils is connected to pulse source of electric energy. The working surfaces of the ferromagnetic and non-ferromagnetic electroconductive part of armature are placed one along another.
