FPV Drone Motor 3115 Brushless Motor Application

The 3115 brushless motor is optimized for high-speed maneuvering racing drones. Its high power density and fast response characteristics meet the instant thrust and precise control requirements of FPV drones.

On FPV drones, the 3115 brushless motor can be used as a standard motor, mainly reflected in:

1. Efficiency improvement design: Adopts multi-slot multi-pole (12N14P) iron core structure and high-performance high-temperature resistant arc magnetic sheets, improving efficiency by more than 5% under heavy load conditions at the rear stage.

2. Speed-torque balance: Uses 4-pole NdFeB rotor design, can provide more than 2 times peak torque at 310V high voltage, while maintaining a wide speed range (KV value 2600-310 optional).

3. Self-cooling structure: Rotor hollow design combined with aviation aluminum shell, matched with active cooling air duct, extending full-load continuous operation time by 50%.

4. Control compatibility: Compatible with U3115S driver chip, supports 200V high voltage input and 500kHz high frequency response, precise dead time control (3-5μs), closed-loop control response delay <10ms, meeting racing mode requirements.

3115 brushless motor focuses on the coordinated improvement of power density, heat dissipation efficiency and mechanical strength, forming significant performance advantages in the FPV drone field.

Huajuntong Motor offers a variety of motors suitable for drones. As the original manufacturer, we have advantages in price and mass production for the 3115 brushless motor. We can also copy various 3115 brushless motor samples on the market, redesign them, and build a new production system.
