Vector Technics 4015 PRO 340KV Brushless Motor

The Vector Technics 4015 PRO 340KV motor is designed to efficiently drive propellers up to 18 inches in diameter. This large propeller compatibility, combined with its low KV rating, makes it ideal for high-torque applications on heavy-lift drones and fixed-wing UAVs where slow-spinning, large props are used for maximum thrust and efficiency.

This motor is rated for a nominal voltage range of 24V to 48V, which corresponds to 6S to 12S LiPo battery packs. Its 340KV winding is optimized for this high-voltage range, providing efficient power and high torque while keeping current draw manageable for extended flight endurance.

You will need a high-voltage BLHeli_32, BLHeli_S, or AM32-based ESC rated for at least 6S to 12S operation and capable of delivering the motor's peak current. Given its max efficiency current range of 20-30A, select an ESC with a continuous current rating of 40A or higher per motor to ensure a safe operating margin and reliable performance.

Yes, the motor features a standard 5mm threaded output shaft, which is widely compatible with common propeller adapters, collets, and direct-mount hubs designed for large multirotor and fixed-wing applications. Always use a secure locking mechanism, such as a nylon-insert lock nut, to prevent prop slippage under high torque.
