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: Layered permanent magnet with conductive cage rotor construction is disclosed. According to one aspect, the subject matter described herein includes a rotor for an electrical machine. The rotor includes a rotor body having a central axis and including multiple permanent magnets positioned to create a plurality of rotor magnetic poles distributed around a peripheral surface of the rotor, and a cage that provides conductive loops around each of the rotor magnetic poles. Each permanent magnet has a magnet body having a center portion and a peripheral portion, the center portion comprising a material having higher remanence than the material comprising the peripheral portion and the peripheral portion comprising a material having a higher coercivity than the material comprising the center portion.

Abstract: A method of monitoring a magnetic orientation of a composite magnetic material injected into a rotor pole of a rotor core. The rotor pole is defined by at least one rotor cavity. The method includes injecting a magnetic composite material into the at least one rotor cavity defining the rotor pole and applying an external magnetic field to the rotor pole to magnetically orient the magnetic composite material during injection into the at least one rotor cavity.

Abstract: A rotor core mold assembly including a rotor stack and a distribution plate. The rotor stack has a top surface and at least one rotor pole defined by a plurality of rotor stack cavities. Each of the plurality of rotor stack cavities has an aspect ratio defined by a width of a respective rotor stack cavity and a longitudinal length of the rotor stack. The distribution plate has a top surface and a bottom surface removably locatable on the top surface of the rotor stack to thereby form a fluid seal. The distribution plate includes a flow channel positioned on the top surface of the distribution plate and extending through the distribution plate, an injection gate in fluid communication with the flow channel, and a plurality of secondary flow channels coupled between the injection gate and the bottom surface of the distribution plate in fluid communication with the injection gate.
