Abstract

PURPOSE:To obtain a long stroke of movement with relatively simple construction, by a method wherein a counter, memory devices and current amplifiers with variable multiplication are inserted into a control system and amplification of the control system varies in accordance with the position of a driving coil. CONSTITUTION:A linear motor is composed of a stator 3 on which magnetic path members 1 are fitted and a driving coil 6 which is composed of two coils 4, 5 the pitch thereof is displaced by a half of a pitch from the pitch of the magnetic path members 1 and which can move in the field made by the magnetic path members 1 freely. When the linear motor is used as a positioning equipment, values which are previously programmed into memory devices 12, 13 by data of the present position which are given by a counter 11 are put into current amplifiers 7, 8 to which an output of the coil 6 is inputted so that amplification varies in accordance with the position of the coils 4, 5. Thus a DC servomechanism system can be established in a whole region of the linear motor and a long stroke of movement can be obtained.
