Abstract: The present disclosure provides a method for producing a magnetic powder and the use of a waste magnetic material for producing isotropic or anisotropic magnets. The method comprises providing a waste magnetic material comprising a waste magnetic chemical composition, analyzing the waste magnetic material to obtain information about the waste magnetic chemical composition thereof, adjusting the waste magnetic chemical composition to a target magnetic chemical composition to obtain an adjusted waste magnetic material, and atomizing the adjusted waste magnetic material to obtain the magnetic powder.

Abstract: Embodiments of permanent magnets and to methods of producing permanent magnets are provided herein. Further, embodiments of electrical machines comprising permanent magnets are provided herein. The method of producing a permanent magnet (200) comprising forming a magnetisable workpiece (100) by additive manufacturing (step A)) and forming the permanent magnet (200) by partitioning the magnetisable workpiece (100), wherein an exposed surface (150) of the permanent magnet (200) formed by the partitioning is non-parallel to the first workpiece layer.

Abstract: A sintered magnet (1), e.g. for an electrical machine, the sintered magnet comprising a core portion (3), a shell portion (2) arranged at an outer part of the sintered magnet, and a diffusion portion (4) arranged at least partially between the core portion and the shell portion. The shell portion (2) has a coercivity, which is at least 30 kA/m larger than the coercivity of the core portion (3). In the diffusion portion (4), the coercivity is not less than the coercivity of the core portion (3) and not larger than the coercivity of the shell portion (2) and the value of the coercivity gradually increases from the core portion (3) towards the shell portion (2). T the thickness of the core portion (3) is not less than 1 mm and the total thickness of the shell portion (2) and the diffusion portion (4) is at least 5 mm.

Abstract: A manufacturing method of a sintered magnet is described. The method comprises forming a pre-sintering body from a first magnetic powder and a second magnetic powder (containing a heavy rare earth element, HRE) so that at least part of the second magnetic powder is provided at at least one inner portion of the pre-sintering body and surrounded from at least two opposite sides by the first magnetic powder; sintering the pre-sintering body; and annealing the sintered pre-sintering body at an annealing temperature lower than the sintering temperature, thereby causing inter-grain diffusion of HRE from the HRE reservoir zone to the grain boundary phase. After the annealing, the grain boundary phase contains the HRE in a higher concentration than the main phase.
