| Low-mass UAV propulsion package | Use SMC axial flux cores when the drone team is trying to trade magnetic core weight into payload, endurance, or thermal margin without losing air-gap control. | Target core mass, propulsion mass basis, baseline radial or outrunner motor, payload target, endurance target, OD, ID, stack height, and excluded components. |
| High-frequency efficiency under drone duty cycles | Compact UAV motors can expose cores to high electrical frequency during hover, climb, and repeated throttle bursts, so loss data must be scoped to the buyer operating point. | Speed, electrical frequency, flux density, waveform, temperature window, sample density, cooling method, and requested B-H or core-loss report format. |
| Hover, climb, and burst thermal margin | A drone propulsion sample is only useful when its thermal assumptions match real mission phases instead of a single nominal motor point. | Duty-cycle timeline, continuous and peak power duration, high-throttle repeat count, ambient temperature, airflow, housing path, and cooldown assumptions. |
| Vibration and prop-imbalance readiness | UAV propulsion components sit close to propeller vibration and rotor dynamics, so flatness, retention, coating, and inspection scope must be defined before flight-test builds. | Expected vibration or shock inputs, propeller class, rotor-stator clearance, mounting datum, retention method, coating/insulation zones, and dimensional inspection plan. |
| Prototype-to-pilot batch consistency | Drone teams often compare samples through bench and flight-test iterations, where uncontrolled batch drift can look like a design change. | Drawing revision, material batch, density target, mass record, sample IDs, inspection sampling plan, magnetic report, packaging method, and pilot quantity. |
| Outdoor handling and corrosion control | Inspection, mapping, agricultural, logistics, and coastal UAV programs can expose cores to humidity, storage, and transport before final motor sealing. | Coating material, masking zones, humidity or salt-fog expectation, handling note, storage condition, export packaging, and destination environment. |
