Permanent Magnets with Integrated Phase Change Materials - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240213834 titled 'Permanent Magnets with Integrated Phase Change Materials
The patent application describes a permanent magnet for use in an electric machine that includes cavities containing a phase change material integrated with the magnet, with the phase transition temperature of the material between 80°C to 200°C and a latent heat of at least 50 kJ/kg. The permanent magnet is composed of a hard magnetic phase, a binder phase, and has an ultimate tensile strength of at least 150 MPa. The magnet is mounted on a rotor of an electric machine and is formed by cold spray additive manufacturing (CSAM).
