HOBBYWING XRotor FPV 3115 1050KV Motor
by HobbyWing

The HOBBYWING XRotor FPV 3115 1050KV is a high-performance, large-scale brushless motor specifically designed for 9-inch to 11-inch FPV drones and heavy-lift cinematic platforms. Engineered to deliver massive torque and structural rigidity, this motor is a premier choice for professional cinelifters and long-range exploration rigs. Its robust design features a high-strength hollow steel shaft and premium EZO bearings, ensuring long-term reliability and ultra-smooth rotation even under the extreme aerodynamic loads of large-diameter propellers.

The motor's internal architecture utilizes high-temperature N52 magnets and precision-engineered stator laminations to maximize efficiency and power output. With a peak power capability exceeding 2900 watts, the XRotor 3115 provides the "punch" needed for technical maneuvers while maintaining the thermal stability required for sustained heavy-lift missions. Every motor is dynamically balanced at the factory to minimize vibrations, ensuring clean telemetry data and crystal-clear cinematic footage.

Key Features

• High-Torque 3115 Stator: Optimized for large-scale FPV quads, providing the grunt needed to spin 9", 10", and 11" props.

• Ultra-Durable EZO Bearings: Equipped with premium Japanese bearings for reduced friction, lower noise, and a longer service life.

• N52 High-Temp Magnets: Features top-tier magnets that retain their strength under high-heat racing and heavy-lift conditions.

• Hollow Steel Shaft: Provides a superior strength-to-weight ratio for the main internal shaft, increasing impact resistance.

• Enhanced Heat Dissipation: The bell design is optimized for airflow, keeping internal temperatures stable during high-throttle operation.

• Standard 19x19mm Mounting: Features a universal M3 mounting pattern compatible with most modern heavy-lift and cinematic frames.
