Description

The Flameback 4006 is a high-torque, low-KV brushless motor designed for UAVs requiring a balance of power, efficiency, and flight stability. Its 40mm stator diameter and 6mm height (4006 size) are optimized for generating significant lift while maintaining a minimal weight footprint. The motor’s advanced electromagnetic design, featuring an 18N24P configuration and precision flux rings, minimizes cogging torque and vibration for exceptionally smooth rotational performance.

Engineered for durability, the motor incorporates a finned aluminum housing that acts as a large heatsink, effectively dissipating heat during prolonged high-power operation. The stator is treated for corrosion resistance, and the assembly is sealed against dust and moisture ingress, making it suitable for mapping, delivery, and aerial photography drones operating in varied climates. When paired with a compatible high-current ESC, such as a 45A 6S unit, and large-diameter propellers (14×4.8 or 15×5.5), it forms a reliable propulsion system for professional-grade UAVs.

Key Features

  • High Thrust-to-Weight Ratio: Generates over 2 kg of thrust from a 72g motor, enabling efficient payload capacity for medium-lift drones.
  • Advanced Thermal Management: Integrated finned housing design maximizes surface area for passive cooling, supporting sustained 350W power output.
  • Precision Rotor Dynamics: 18N24P configuration combined with balanced flux rings reduces magnetic cogging and vibration for smoother flight control.
  • Rugged Environmental Sealing: Protected construction resists dust, moisture, and corrosion, ensuring reliability in outdoor and coastal operations.
  • High-Current Capability: Rated for continuous 18A current with 18 AWG silicon wires, compatible with high-discharge 4-6S LiPo batteries.
  • Wide Operating Temperature: Functions reliably in ambient temperatures from -20°C to 125°C.
  • Optimized System Integration: Designed to pair seamlessly with Flameback 45A ESCs and large-scale propellers for complete propulsion solutions.

Applications

  • Medium-lift delivery and logistics drones requiring reliable thrust and endurance.
  • Aerial photography and mapping UAVs (e.g., fixed-wing or multirotor) where stable, vibration-free flight is critical.
  • Heavy-lift FPV platforms and industrial inspection drones operating on 4-6S power systems.
  • Custom-built agricultural or surveying drones needing corrosion-resistant components for outdoor use.

Frequently Asked Questions

What is the recommended propeller size for the Flameback 4006 320KV motor?

For optimal performance with this low-KV motor on 4-6S LiPo batteries, large-diameter, low-pitch propellers are recommended. Typical pairings include 14x4.8 or 15x5.5 propellers, which efficiently convert the motor's high torque into thrust suitable for medium-lift UAVs.

Can this motor be used with a standard 30A or 40A ESC?

While a 30A ESC may suffice for conservative throttle use, the motor is rated for a continuous 18A draw and can experience higher peak currents. For full performance and safety, pairing it with a dedicated high-current ESC, such as the recommended Flameback 45A 6S ESC or an equivalent, is strongly advised to handle potential spikes and ensure reliable operation.

Is the Flameback 4006 motor suitable for wet or dusty environments?

Yes. The motor features a sealed construction designed to protect against dust and moisture ingress. Combined with a corrosion-resistant stator treatment, this makes it a reliable choice for drones operating in humid, coastal, or otherwise challenging outdoor conditions common in agricultural, surveying, and delivery applications.
