The ePropelled SG6000 starter generator is designed for UAV applications. It has a slim, lightweight design with active air cooling that allows it to operate up to 180°C. It uses a patent-pending bearingless mounting system and has high power density. Specifications include a diameter of 7.32 inches, weight of 5.4 pounds, and peak power output of 8% below its rated maximum continuous power for 5 minutes. It requires consistent airflow of at least 2m/s to maintain performance levels.

Starter Generator - SG6000
UAV manufacturers face a complex set of trade-offs to meet the performance
requirements for any given application. The permanent magnet brushless starter
generator is a critical component for ensuring the electrical system can meet the
design objectives of the UAV.
ePropelled SG series are the most versatile starter generators in their category.
The slim line design boasts a patent pending active air-cooling system that
allows it to operate in temperatures in excess of 180°C in certain applications.
Our unique patent pending adaptor allows bearing less mounting of the starter
generator directly onto the engine.
Low Weight
The outer rotor boasts the lowest weight in its class with outstanding power density.
• Bearingless option available with dedicated Spyder mounting jig
• Directly driven on engine crankshaft with customizable shaft coupling ring
• Optional customizable active air-cooling rotor hub
• Optional K-type thermal sensor to measure winding temperature
ePropelled offers a range of electrical system components, such as intelligent Power
Systems (IPS), that are engineered to work with these starter generators.

The starter generators require consistent (open) airflow of 2m/s, or larger, across
the windings to maintain the maximum continuous current and power ratings stated
during runtime. The figures in this document are provided as guidelines for normal
conditions and device operation; environmental factors, such as air temperature
and/or humidity, can vary the starter generators maximum performance limits.
Ambient temperature during testing, 25°C
Please ensure that the starter generator is used within an environment that does not
exceed its safe operational temperature of 180°C for the windings, 180°C for the rotor
and 120°C for the bearing in bearing version.
Tests carried out at mean sea level (altitude 0ft) and 89% Humidity.
