Innovations in Axial Flux Permanent Magnet Motor Thermal Management for High Power Density Applications

For aerospace applications, power density is a major driving force in the design of electrified powertrains. At forefront challenging electric motors with high efficiencies, torque, and capabilities. Due to its performance, Axial Flux Permanent Magnet (AFPM) Motor expected be one leading technologies meet demands these industries. Finding balance between cooling system’s effectiveness subsequent parasitic losses key utilizing performance benefits. Single stator double rotor topologies achieve best torque lower losses, however are more cool as center motor. single machines less but typically have density. Rotor air discussed including blades, meshes, vents which can optimized prevent demagnetization. Stator critical many maximize current producing large amount heat. The chosen strategy depends on machine topology accomplished by several strategies, jackets, fins, channels, immersion cooling, hollow coils, heat pipes.
