Method for manufacturing of magnet poles

摘要

A method for manufacturing sintered magnet poles is described. The mould is filled with a vitrifiable base material powder and closed with a plate. A magnetic field aligns the powder and a plate pressed onto the powder establishes a compact that holds the alignment in place. The compact is sintered to form a sintered magnet pole. The mould forms a protective cover of the sintered magnet pole and the plate forms a base plate of a magnet pole piece. Furthermore, a magnet pole piece is provided which has a magnet pole and a base plate which is fixed to a protective cover so that the base plate and the protective cover surround the magnet pole. The base plate and/or the protective cover of the magnet pole piece has at least one element that provides a geometrical locking of the magnet pole to the base plate and/or the protective cover.
