MOVER OF LINEAR MACHINE

摘要

PURPOSE: The mover of the linear instrument uses a plurality of permanent magnet pieces combined in the outer circumference of the sub core. The effect of the permanent magnet magnetized to the radial direction is obtained. CONSTITUTION: In the central part of the mover shaft(110), a plurality of sub cores of the ring type is fixed. A plurality of permanent magnet pieces(130) forms the permanent magnet body of cylindrical. It leaves the spacer(140) in interval and the permanent magnet piece is arranged according to the axial direction of the mover shaft.
