The transition to ultra-high-power-density aviation and space mobility relies heavily on superconducting machines. However, the fundamental contradiction between cryogenic main tenance and catastrophic quench thermal-runaway remains a critical bottleneck. This work reframes the electromagnetic control of electric machines as a programmable thermodynamic actuator capable of driving magnetocaloric heat pumps. We pro pose a novel conceptual architecture for a completely solid-state thermal management system in high-speed superconducting mo tors (up to 10,000 RPM). A multi-stage cascaded Active Magnetic Regenerator (AMR) utilizing an “onion” stator topology (La-Fe Si, Gd, ErCo2) is introduced. Diverging from traditional AMR, this system leverages a vector-modulated magnetocaloric cycle, effectively embedding a solid-state magnetocaloric traveling-wave peristaltic pump directly within the motor stator. To ensure survivability during 1500 W quench anomalies, a mechanical interference-fit thermal fuse is conceptualized as a passive sacrificial fail-safe. Furthermore, a complex-vector decoupled Field-Oriented Control (FOC) achieves near-zero torque ripple (< 0.5%) during 5 kHz thermodynamic carrier excitation. Multiphysics continuous-domain evaluations rigorously validate the thermodynamic self-bootstrapping, spatial quench isolation, and decoupled mechanical output.
