ePropelled has the broadest range of electric propulsion systems for mission-critical UAV applications.

Our electric propulsion systems family includes propulsion motors, ranging from 500 watts to 20 kW, and matching motor controllers.

Fly Higher, Fly Longer, Fly Smarter

ePropelled high-performance systems are designed and built in the United States for commercial, security, and defense uses to meet the needs of the most demanding applications. Standard products are available off the shelf to simplify your build processes, but we can also alter designs according to your specific requirements.

Our systems feature:

  • unique cooling technology to enable UAVs to fly higher in thinner air where cooling is a challenge, 
  • best-in-class power and thrust-per-weight ratio to meet challenging mission parameters, and  
  • smarter systems—using standards-based CAN—that provide access to all sensor data. 

Propulsion Motors

Our propulsion motors set a new standard for performance. The innovative design of our high-efficiency motors provides the best thrust-to-weight ratio in their class and our advanced cooling technology allows UAVs to fly higher.

Motor Controllers

ePropelled intelligent motor controllers are paired with our motors to provide a complete propulsion solution. These controllers are designed to enable advanced electric propulsion systems for the most demanding applications.

Starter Generators

Starter Generators use the mechanical energy from the internal combustion engine (ICE). ePropelled has a family of starter generators ranging from 500 Watts to 12 kW. While our SGs provide the same power generation as an alternator, they have enough torque to start the engine. When paired with our power electronics, the SGs can also support hybrid applications.


Intelligent Power Systems

ePropelled’s Intelligent Power Systems take the AC generated by the SG and convert it to DC to power the onboard systems. The iPS also gathers sensor data and provides access via an industry-standard CAN bus.


Electronic Engine Starters

The Electronic Engine Starters use an onboard battery to send power to the starter generator to start the engine. This allows the UAV to be completely self-contained. The EES also allows the SG to function as a battery-powered motor for hybrid applications including power assist for take-off and extended range for emergency landings.
