LN4214

Category

LN4214 is a 380KV high-torque brushless motor built for industrial UAVs. Supporting 6S–12S LiPo and up to 13″ -15″propellers, it delivers strong thrust, stable performance, and excellent efficiency for long-endurance flights.

Description

The LN4214 Brushless Drone Motor is engineered for industrial-grade UAVs that require strong thrust, stable performance, and high-efficiency power output. With a KV rating of 320 and a robust stator design, this motor is ideal for heavy-lift drones used in agriculture, surveying, mapping, aerial inspections, and logistics delivery.

Supporting 6S–12S LiPo batteries and propellers up to 15 inches, the LN4214 delivers high torque and consistent performance across a wide range of operating conditions. Its efficient power-to-thrust ratio allows for longer flight durations, better payload control, and reduced energy consumption—making it perfect for mission-critical drone applications.

Constructed with precision CNC-machined aluminum housing, high-temperature magnets, and low-resistance windings, the motor ensures durability and thermal stability under continuous high-load operations. The motor also undergoes dynamic balancing and vibration reduction to enhance flight stability, reduce noise, and protect drone-mounted sensors or cameras.

Thanks to its strong structural integrity and versatile compatibility, the LN4214 is widely used in professional UAV platforms that demand both performance and endurance. Whether you’re building new systems or upgrading an existing fleet, this motor offers a reliable, efficient, and future-proof propulsion solution.

Choose the LN4214 for a balanced combination of power, precision, and industrial-grade reliability, trusted by drone manufacturers and developers around the world.
