3115 FPV Motor

The 3115 FPV motor is a large-stator brushless motor typically used for high-torque applications such as long-range, cinematic, and heavy-lift drones. It is characterized by its 31mm stator diameter and 15mm stator height, providing the necessary power to drive 7-inch to 10-inch propellers effectively.

• High Torque Output: Optimized for large prop setups (up to 12 inches), delivering high thrust at lower RPMs for stable cinematic flight.
• Enhanced Durability: Many models feature reinforced components like CNC-machined aluminum bells, titanium alloy shafts, and N52H arc magnets to withstand the rigors of heavy-duty FPV use.
• Advanced Cooling: Designed with open bases or proactive heat dissipation structures (like split exhaust blades) to maintain low operating temperatures during long-endurance flights.
• Precision Flight: Uses high-quality Japanese NMB or NSK bearings to ensure smooth, low-vibration rotation and precise throttle response.
• Wide Voltage Compatibility: Most 3115 motors are rated for 6S LiPo setups, though some variants support 3S to 12S depending on the KV rating.

• Stator Dimensions: 31mm (Diameter) x 15mm (Height).
• Configuration: Typically 12N14P (12 stator arms and 14 rotor poles).
• Shaft Diameter: 5mm (M5 thread) is the standard for propeller mounting.
• Weight: Generally ranges from 105g to 125g including wires, though some specialized "lite" versions exist at ~58g.
• Mounting Pattern: Standard 19mm x 19mm or 16mm x 16mm using M3 screws.
• Max Power: Can reach between 1600W and 2100W depending on the KV and input voltage.
