Abstract
Apparatus for magnetizing permanent magnet bodies to provide them with narrow magnetic poles of alternating polarity consists of arranging an array of pairs of magnetizing conductors in such a manner that when each of the two conductors of each pair are connected in series each of the pairs of conductors can be connected in parallel directly to the two common magnetizing current supply leads.
Claims12
Apparatus for magnetizing a permanent magnet body to produce magnetic poles of successively alternating polarities on at least one surface of the body, comprising:
- an array of pairs of elongated electrical conductors to be disposed in close proximity to said surface to be magnetized, the conductors of each pair being laterally spaced from each other and each of the pairs of conductors being laterally spaced from each other to define in the spaces between conductors of each pair a magnetic pole of one polarity and to define in the spaces between adjacent pairs of conductors a magnetic pole of the opposite polarity;
- a pair of magnetizing direct current supply leads disposed in a predetermined path along a first portion of said array;
- one end of each of the conductors in each of said pairs of conductors being connected to a respective one of said pair of current supply leads at said first portion of said array;
- the other ends of each of the conductors in each pair of conductors being connected to each other at a location in said array remote from said first portion and having at said remote location the same electrical potential in each of said pairs of conductors, and;
- a bridge conductor connected to all of said pairs of conductors at said remote locations.
