Abstract:
A method for manufacturing sintered magnet poles is described. A vitrifiable base material powder is filled into a mold, the mold is closed with a plate, the mold with the powder is placed in a magnetic field for aligning the powder, the plate is pressed such onto the powder as to establish a compact that holds the alignment in place, and the compact is sintered so as to form a sintered magnet pole. The mold ultimately forms a protective cover of the sintered magnet pole and the plate ultimately 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.
