M 6208 UL
6208-155KV/310KV
Industrial-level Multi-rotor UAV Motor
Reliable and Efficient,
Ideal for Long Endurance.
Designed for high-end industrial-grade multi-rotor drone applications. It is widely used in aerial
photography, surveying, monitoring, inspection, public safety and other scenarios.
The Sharp and Distinct Edges
Stands Out Remarkably
The rotor is well balanced, featuring
an ultimate hollow design for maximum
weight reduction. The motor weighs 165g only.

Sharp and distinct edges, presenting a
dynamic beauty.
Craftsmanship
Manual winding, high groove full rate effectively reduces resistance,
lower motor temperature rise and higher efficiency
Excellent Material Selection,
Outstanding Performance
Silicon steel sheets imported from
Kawasaki, Japan are punched into high
-performance iron cores
The efficiency
data is even better.
The magnetic circuit is
optimized for common
working conditions
200℃
high-temperature
resistant enameled wires.
