Abstract

The iron core of the magnetic disk magnetic source is tiled with a plurality of layers of polarity reversible AlNiCo magnetic steel, so that the required overturning current is reduced when the magnetic coil is charged and demagnetized. Under the condition of disk power failure, it is completely dependent on the permanent magnetic force produced by magnetic steel, and has no temp. rise suction positioning; different from the traditional electric control permanent magnetic disk: it can also continuously supply forward current to make the electromagnetic magnetic force lines and permanent magnetic force lines mutually extrude, and can make the magnetic disk produce super strong synthetic magnetic force when the small current is supplied.
