High Efficiency & Endurance
The M4006 UL is optimized for a recommended pulling force of 1.0 kg per rotor.
It supports quadcopters with a total takeoff weight of 2.4–4.0 kg.
This motor is designed to provide long flight times, stable operation, and efficient power delivery for professional UAV missions.
Precision Engineering
The new hollow rotor design improves visual recognition while reducing overall motor weight.
The knurled shaft helps prevent loosening and improves long-term reliability.
The optimized magnetic circuit reduces harmonics, allowing smoother ESC matching and more stable operation.
Durability & Reliability
Waterproof bearings with low friction torque help extend the motor’s service life.
The high-toughness carbide shaft provides extra strength and improved durability.
The 0.2 mm low-loss silicon steel core reduces energy loss and improves efficiency.
The outer rotor casing is made from 20# seamless steel tube with nickel electrophoresis treatment for enhanced anti-corrosion protection.
Attention to Detail
The integrated stator seat and back cover reduce unnecessary parts and simplify the overall structure.
The tail spindle uses a spring and screw interlock design for foolproof reliability.
Anti-rust screws improve long-term durability in demanding operating environments.
