Product Overview

This 8120 95KV 12S outrunner brushless motor is professionally developed for heavy-load, long-endurance industrial multi-rotor UAVs. Adopting mature disc-type outer rotor structure and strict production testing standards, it delivers stable high torque output, low power consumption and ultra-low vibration during continuous heavy-duty operation. Perfect match for 6-axis large plant protection drones, aerial mapping inspection UAVs, low-altitude cargo delivery aircraft and other large-scale multi-copter platforms.

Core Advantages & Craftsmanship

1. Premium CNC Machined Housing

The whole motor shell is fully processed by CNC aviation aluminum alloy with fine surface finishing. Strict dynamic balance calibration greatly reduces resonance and shaking at high rotating speed. Hollowed stator slot design optimizes passive heat dissipation, effectively avoiding overheating and magnetic demagnetization under long-time full-load working status.

2. High-Grade Internal Components

Rotor Magnet: High-performance neodymium iron boron permanent magnet, strong magnetic flux, excellent resistance to high-temperature demagnetization;
Stator Coil: Reinforced by epoxy resin pressure pouring, great insulation, heat resistance and anti-vibration performance to prevent wire breakage;
Drive Shaft: High-strength alloy steel main shaft, matched with top and bottom sets of precision high-speed ball bearings, minimizing mechanical friction loss, outstanding anti-impact and stable high-speed support capacity.

3. Rigorous Quality Testing

Each unit passes comprehensive durability tests including static load, dynamic tension, high-temperature aging, continuous vibration and full-power long-time running. Featured with long service life, high energy conversion efficiency, low no-load current, quiet operation and linear throttle control experience.

Warm Tips

Please use 12S standard lithium battery for power supply, do not overvoltage to avoid burning the motor winding;
Tighten all mounting screws evenly during installation to prevent loose parts caused by high-frequency vibration;
Regularly check bearing flexibility and wire insulation condition after long-term heavy load use to extend service life;
Professional assembly and debugging are suggested for industrial UAV application.
