AI Technical Summary
Existing electric machines face challenges in achieving a high power-to-weight ratio and efficient cooling, particularly in permanent magnet synchronous machines, leading to potential demagnetization and heat-related damage due to inadequate cooling systems.
A fluid-cooled, multiphase permanent magnet synchronous machine with a stator and rotor configuration that includes a heat-conducting layer extending from permanent magnet elements to the rotor shaft, featuring cooling fluid channels and a support structure for thermal energy transport, allowing for efficient heat dissipation in both internal and external rotor configurations.
The design achieves a high power-to-weight ratio and minimal installation space with effective cooling, reducing the risk of demagnetization and maintaining operational efficiency even at high speeds.
