Abstract
A permanent-field armature for an electrical machine includes an armature body having internal magnet pockets, and a plurality of permanent magnets having a magnetization for generating a magnetic field and disposed in the magnetic pockets in one-to-one correspondence. The armature body guides the magnetic field between the magnet pockets and magnetic poles of the armature on an armature surface. Each magnet pocket is formed for guiding the magnetic field in a material which has at least one area having a magnetic anisotropy with an easy axis and a hard axis of magnetizing capability, with the easy axis being aligned in parallel relation to or at least at an angle of less than 25° to a magnetization direction of the magnetization of the permanent magnet disposed in the magnet pocket.
