High-Efficiency, Reliable Electrical Subsystems for Cryogenic Pumps

Beacon Industries Inc. proposes a high-efficiency motor drive and control system designed to improve the performance and reliability of cryogenic pumps used in deep-space and planetary exploration. The system combines a superconducting motor drive using ReBCO-based coils with Ga₂O₃-based high-frequency switching devices and an advanced field-oriented control (FOC) system. The superconducting motor eliminates resistive losses at cryogenic temperatures, reducing power consumption and increasing efficiency. Ga₂O₃-based transistors provide faster and more efficient power modulation, improving load response and reducing switching losses. The FOC system dynamically adjusts motor speed and torque based on real-time load changes, ensuring stable performance even under extreme conditions. This solution is designed for use in NASA’s lunar and Martian surface operations, the Lunar Gateway, and deep-space transport missions. The proposed technology will reduce operational costs, increase system lifespan, and improve reliability in harsh space environments.
