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: 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: The present disclosure relates to a motor. The motor can include a stator defining an interior space, a rotor disposed in the interior space of the stator. The rotor can include a body defining a structure and a plurality of magnets disposed in the plurality of cavities. In some embodiments, the structure defines a plurality of cavities in the body of the rotor, the plurality of cavities includes at least a first cavity and a second cavity, the first cavity is spaced radially outward from the second cavity, and a thickness of the first cavity is larger than a thickness of the second cavity. In some embodiments, at least some of the cavities of the plurality of cavities have a magnet from the plurality of magnets disposed therein.
