Overview of Fixed-Wing UAVs

A fixed-wing UAV is an unmanned aerial vehicle that generates aerodynamic lift through fixed wings installed on the fuselage and relies on a power system to provide forward thrust, enabling autonomous or semi-autonomous flight. It is a core UAV category distinct from multi-rotors, helicopters, and vertical takeoff and landing (VTOL) aircraft.

Compared with other aircraft types, fixed-wing UAVs have core advantages such as fast cruise speed, long flight range, high flight efficiency, and strong payload capacity. They can meet the full-spectrum needs from small hand-launched aerial surveying models to medium and large long-endurance operational models.

Fixed-wing UAVs are mainstream flight platforms for global civil mapping, industrial inspection, emergency rescue, logistics and transportation, and special operations scenarios. Currently, the global fixed-wing UAV industry is accelerating the transition from fuel power to all-electric power, and high-performance drive motors have become core components determining the overall performance of the aircraft.

Core Requirements for Drive Motors in Fixed-Wing UAVs

Fixed-wing UAVs are mostly used for outdoor long-endurance and long-distance operations, being professional equipment requiring high reliability and environmental adaptability, thus imposing stringent industry standards on drive motors:

Extreme Lightweight

Fixed-wing UAVs are highly sensitive to overall weight, requiring motors to output sufficient power and thrust within limited volume and weight.

High Efficiency

Long endurance is the core competitiveness of fixed-wing UAVs, requiring motors to maintain high energy conversion efficiency under full working conditions including no-load, cruise, and full-load climb.

Strong Environmental Adaptability

Adaptable to a wide temperature range of -20℃ to 60℃ and high-altitude low air pressure, with no obvious performance degradation during long-term continuous operation, supporting thousands of hours of trouble-free operation.

Low Electromagnetic Interference

Motor vibration directly affects the working accuracy of high-precision payloads such as airborne aerial survey cameras, mapping radars, and reconnaissance sensors; meanwhile, motors are required to have no obvious electromagnetic interference.

Excellent Dynamic Response

Capable of smooth speed regulation within a wide speed range and quick response to flight control system commands.

Standardized Design

Adopt industry-standard installation and interface designs for fast adaptation to mainstream propellers, ESCs, and flight control systems.

Irreplaceability of Outrunner Brushless DC Motors

In power solutions for electric fixed‑wing UAVs, outrunner brushless DC motors offer comprehensive advantages that other mainstream options—such as brushed DC motors, brushed coreless motors, and brushless coreless motors—cannot match. Their structural design and operating principles make them inherently more suitable for demanding flight environments.

With higher efficiency, stronger torque output, better heat dissipation, and significantly improved reliability, outrunner brushless DC motors align perfectly with the long‑endurance, high‑stability, and high‑performance requirements of fixed‑wing UAV applications.

Comparison with Conventional Brushed DC Motors

Conventional brushed DC motors use carbon‑brush mechanical commutation, which produces electric sparks and strong electromagnetic interference. This interference can disrupt the stable operation of fixed‑wing UAV flight‑control systems and onboard high‑precision payloads.

Carbon brushes also wear out easily, leading to higher failure rates and frequent maintenance. As a result, brushed motors cannot meet the long‑endurance and high‑reliability requirements demanded by modern fixed‑wing UAV applications.

Comparison with Brushed Coreless Motors

Although brushed coreless motors feature ironless, low inertia, and lightweight properties, they still adopt a mechanical commutation structure and cannot overcome the lifespan limitations and electromagnetic interference caused by carbon brush wear.

Meanwhile, the coreless winding has poor heat dissipation paths, is prone to overheating damage under continuous high-load operation, and has weak overload capacity and low power output limit. They are only suitable for small, light-load micro fixed-wing UAVs and cannot support the continuous power demand for medium and long-range flight.

Comparison with Brushless Coreless Motors

Although brushless coreless motors eliminate the drawbacks of mechanical commutation and feature low inertia and fast response, their windings have no iron core support and long heat dissipation paths. They heat up quickly under high-current full-load operation, are prone to permanent magnet demagnetization, and lack sufficient power density and overload capacity.

In addition, they have high structural customization difficulty, high production costs, and high mass production thresholds, only applicable to ultra-small fixed-wing models requiring extremely high response speed.
