Permanent magnet arrangement, preferably for rotors of permanently stimulated synchronous machines, has individual magnet blocks of different heights at different depths in iron

摘要

The arrangement has poles of at least two individual magnet blocks, in which the individual magnet blocks are of different heights. The individual magnet blocks (3) are mounted at different depths in the rotor iron (2). There is a constant mechanical air gap (4) to the stator at the magnet block edges and the height of the individual blocks decreases towards the pole edges.
