LETU 4214 380KV Brushless Motor — for 13-15″ X-Class, Heavy-Lift & Cinelifter Drones

Description

Engineered for Heavy-Lift UAV Propulsion

The LETUMOTOR 4214-380KV is a high-voltage brushless motor purpose-built for heavy-lift multi-rotor platforms. With a 42mm stator, 380V-rated high-voltage architecture, and precision-engineered 12N14P configuration, it delivers the consistent, efficient, and powerful thrust that agricultural spraying, cargo delivery, and industrial mapping drones demand.

Key Specifications

Key Performance Highlights

• 6170g Max Thrust: Exceptional lifting capacity for heavy-payload missions, with 450W rated output power for sustained, efficient operation.

• 380V High-Voltage Architecture: Designed for high-voltage power systems to minimize current loss, reduce wiring heat, and extend overall flight endurance.

• 12N14P Precision Configuration: High torque density and smooth rotation for stable, efficient, and responsive propulsion across the throttle range.

• 65mΩ Low Internal Resistance: Minimizes energy loss, improves efficiency, and reduces operating temperatures under heavy loads.

Engineered for Industrial Reliability

• 220°C Class H Winding Insulation: High-temperature enameled copper windings maintain stable performance under sustained heavy loads and demanding environmental conditions.

• 180°C Magnet Grade: High-grade magnets maintain consistent magnetic performance and resist demagnetization in high-heat flight environments.

• Precision Dynamic Balance: Factory-balanced rotor minimizes vibration, improves flight stability, and extends airframe component life.

• Premium Sealed Bearings: High-quality bearings deliver smooth, low-noise rotation and long service life.

Designed for Professional Integration

• Standardized Mounting: 4x M4-Ø30mm motor mount and 4x M4-Ø25.5mm prop mount for broad compatibility with professional airframes.

• 14AWG 500mm Leads: Heavy-gauge, long-length motor leads provide clean, secure electrical connections and flexible installation.

• 6mm Shaft with M6 Thread: Precision steel shaft with threaded tip ensures reliable torque transfer and secure propeller locking.
