What You Can Do

You can upload flywheel operational datasets and receive comprehensive analysis of efficiency losses across bearing friction, magnetic drag, aerodynamic losses, and thermal management. Claude diagnoses root causes of performance degradation, predicts component failure timelines using bearing wear and stress patterns, and models the impact of specific optimizations—such as bearing upgrades, magnetic field reconfigurations, or vacuum improvements—on system efficiency and ROI. This multi-domain analysis helps you prioritize interventions by cost-effectiveness and operational impact.

Features

Efficiency loss decomposition

isolate contributions from bearing friction, magnetic losses, aerodynamic drag, and thermal dissipation

Bearing wear prediction

analyze degradation patterns to forecast failure timelines and schedule maintenance proactively

Rotor dynamics modeling

assess imbalance, vibration, and structural stress impacts on performance and safety

Thermal management assessment

diagnose cooling inefficiencies and model temperature effects on rotor stability

Optimization impact modeling

quantify efficiency gains from design changes (bearing upgrades, magnetic configurations, vacuum levels)

Specification validation

compare measured performance against design targets during commissioning and post-maintenance

ROI calculation

evaluate competing optimization strategies by cost, efficiency improvement, and payback period
