Welcome to wholesale bulk cheap bldc-s3115 motor in stock here from our factory. Customized orders are welcome.
Positioning of 3115 motor
The 3115 motor is designed for 9-10 inch heavy-duty long-range FPV drones, serving as an upgraded version of the 28 series. It balances stronger load capacity, extended range, and longer operation time, making it a versatile mid-to-large power solution.
Powerful performance,efficient cooling
The rotor employs a 14-pole arc-shaped magnet, featuring high torque density and strong low-speed output, delivering greater torque for the motor. The hollow inner wall of the rotor and detachable top cover ensure efficient heat dissipation, preventing overheating even during heavy-load continuous flight, while extending maximum operating time by over 50% under full load.
Outstanding performance
The outer layer of the stator utilizes high-performance 0.2mm silicon steel sheets, while the inner layer employs a multi-strand enameled wire winding design in addition to being wrapped with 220°C high-temperature heat-resistant paint, increasing the slot fill rate by approximately 5% or more to meet users' demands for ultimate power performance.
Anti-slip groove design
To achieve safer and more efficient flight, we designed anti-slip grooves on the motor's propeller mounting bracket to prevent propeller slippage.
