Magnet Force―For multipole magnetizing and pattern magnetizing of permanent magnet―

Magnetizing Yoke
●Have distinguished durability for high voltage /heavy-current power from magnetizing electric
power supply to do a vacuum mold in epoxy resin.
●With superior material of magnetic properties,
show high performance by the most suitable
magnetic circuit design.
●High takt continuous service in a production line ispossible by using a water-cooled chiller.
●We can do design and manufacture of magnetizing
yoke in wide line up such as ferrite magnet use, rareearths magnet use.

About magnetizing yoke
1. Principle of magnetizing yoke
1) Call the jig which wrapped an iron core (a yoke) with a coil amagnetizing yoke. Turn on electricity in a magnetizing yoke inheavy-current of a pulse to output from a magnetizing electric
power supply. (Cf. right drawing.)
Current value is tens of thousands of amperes from several
thousand amperes. The time-current characteristic that anelectric current flows through is several hundred miliseconds
from several miliseconds. (Change by a specification of a coil)2) When an electric current flows through magnetizing yoke,strong pulse magnetic field occurs from a coil. The part whichattached a coil of a magnetizing yoke (magnetic pole) becomesa powerful electromagnet.
3) When a permanent magnet of non-magnetizing is set at thepart which attached a coil of a magnetizing yoke, be done
magnetizing. Magnetic pole pattern done magnetizing ofbecomes same as magnetic pole pattern of a magnetizing yoke.
2. The magnetic field which occurs with a magnetizing yoke1) In the case of a magnetizing yoke with 4 pole magnetizing asa ring type magnet such as the right drawing, an N pole (thepole which a magnetic flux discharges) and an S pole (the pole
which magnetic flux is incident on) are posted in turn.
2) As for the magnetized permanent magnet, polarity of an Npole (the pole which a magnetic flux discharges) of amagnetizing yoke side becomes an S pole (the pole whichmagnetic flux is incident on). Therefore, as for the opposite
face of a magnetizing yoke side, polarity is reversed.
Attention!
Magnetic pole pattern of a magnetizing yoke and magnetic
pole pattern of a magnetized permanent magnet are planesymmetry.
