Permanent-field armature with guided magnetic field

A permanent-field armature for an electrical machine, said permanent-field armature comprising:

• an armature body having internal magnet pockets forming a magnetic circuit in a radially interior area of the armature body;
• 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, said armature body being configured to guide the magnetic field between the magnet pockets and magnetic poles of the armature on an armature surface, each said magnet pocket being 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, said 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,
• wherein the armature body is formed from a number of segments such that the easy axis at each of the segments is aligned separately from the other ones of the segments,
• wherein at a contact surface between two of the segments, the easy axis of one of the two segments and the easy axis of the other one of the two segments are disposed in parallel relation or at least at an angle of less than 25° to one another, thereby being tangentially or laterally disposed,
• wherein the magnetic circuit is closed in the radially interior area of the armature body, so that a leakage flux in a radially inner area of the radially interior area is reduced.
