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

propose a novel conceptual architecture for a completely solid

state thermal management system in high-speed superconducting

motors (up to 10,000 RPM). A multi-stage cascaded Active Mag

netic Regenerator (AMR) utilizing an “onion” stator topology

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 Con

trol (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 mechan

ical output.
