About
About ePropelled
ePropelled develops motors, electronic speed controllers, starter-generators and power-management technology for electric and hybrid aircraft. Its Sparrow, Falcon and Hercules ranges address different aircraft sizes, from smaller UAVs to larger uncrewed and advanced-air-mobility platforms. Matching motor and controller products are designed around required thrust, voltage, propeller speed, cooling and fault behaviour.
The ePConnected software layer links propulsion components with monitoring and adaptive control. It can report temperature, voltage, current and motor state while adjusting power behaviour around the mission and available energy. Aircraft manufacturers integrate these components with their battery, propeller, flight-control and safety systems; ePropelled also provides engineering support for custom windings, mechanical interfaces and hybrid architectures that use a generator to extend range or supply onboard electrical loads.

Timeline
Events
- 2026-08-11 - Contract Award - ePropelled announces government-backed U.S. manufacturing expansion
Funding comes through the Industrial Base Analysis and Sustainment program. The company expects propulsion-system production capacity to rise by more than fourfold. Full operation is expected after facility upgrades and equipment installation.
Source - 2026-08-04 - Regulatory - ePropelled achieves ISO/IEC 27001:2022 certification
Coverage includes research, engineering and manufacturing facilities in the United States, United Kingdom and India. The audited framework manages confidentiality, integrity and availability risks. The certification complements the company's existing ISO 9001:2015 quality-management certification.
Source - 2026-07-20 - Product Launch - ePropelled introduces SKYLARK motor-controller units
The integrated unit reduces wiring and connections during aircraft assembly. Onboard ePConnect links the system to matched motors, controllers and power systems. The design targets compact packaging, faster assembly and increased payload capacity.
Source - 2026-07-20 - Product Launch - ePropelled introduces eP Unified Architecture and ePLink
ePLink enables firmware updates, configuration, diagnostics and secure data exchange. The architecture connects motors, controllers, starter-generators and intelligent power systems. Expanded DroneCAN and SAE J1939 support remained under development.
Source - 2026-05-13 - Product Launch - ePropelled launches integrated propulsion system for agricultural drones
The system combines brushless motors, electronic speed controllers and intelligent power management. Thermal management is designed for sustained operation around dust, chemicals and variable temperatures. The architecture supports both monitoring drones and heavy-lift spraying or spreading platforms.
Source - 2026-04-09 - Capability - ePropelled expands Hercules hybrid power configurations
The announced platform spans approximately 500 W to 12 kW. CAN interfaces and open APIs expose voltage, current, speed, temperature and power monitoring. OEM options include mounting formats, control interfaces and application-specific power management.
Source - 2026-03-20 - Facility Opening - ePropelled opens expanded Coventry Global Innovation Centre
At the announcement, annual production was around 100,000 to 150,000 propulsion systems. Output above one million systems annually by 2027 remained a company target. The UK site supports engineering and validation within a global operations network.
Source - 2026-03-03 - Capability - ePropelled expands motor controllers and intelligent power systems
ESCs complement Sparrow and Falcon motors with torque, speed and diagnostic functions. Hercules intelligent power systems regulate and distribute energy to propulsion, avionics, sensors and payloads. The portfolio is designed to coordinate motors, controllers and hybrid power units within one system.
Source - 2026-01-13 - Partnership - Hirth Engines and ePropelled announced hybrid-propulsion collaboration
The planned architecture combines Hirth two-stroke engines with ePropelled starter generators, electronic engine starters and intelligent power systems. Research, development and system-integration work had begun, with prototype demonstrations expected in upcoming project cycles. Target applications include surveillance, advanced air mobility and lightweight hybrid ground vehicles.
Source - 2025-12-09 - Product Launch - ePropelled adds APM 1404, 2207.5 and 3115 to Sparrow lineup
APM 1404 targets micro-UAVs and short-range ISR platforms. APM 2207.5 balances torque and compact packaging for small tactical platforms. APM 3115 targets higher-power loitering, ISR and hybrid applications; all three models were available online.
Source - 2025-08-20 - Production Milestone - ePropelled expands its Laconia propulsion manufacturing hub
The Laconia facility was planned to reach 24,000 square feet, following the start of production in late 2024. Its manufacturing lines cover the Sparrow, Falcon and Hercules propulsion ranges, with coil winding, rotor assembly, balancing and final assembly. In-house lamination production and a machine shop were planned for 2026.
Source - 2025-08-05 - Partnership - USA Rare Earth and ePropelled agree to develop magnets for uncrewed-system motors
USA Rare Earth will begin prototyping the magnets at its Oklahoma manufacturing plant. The proposed applications span ePropelled motors and power systems for uncrewed air, land, and sea vehicles. The companies described a future supply and purchase relationship subject to development and qualification.
Source - 2025-04-08 - Product Launch - ePropelled launches Sparrow Series propulsion motors for UAVs
The Sparrow Series includes multiple motor and controller options. Applications include long-duration flights, mapping, surveillance, rescue, inspection, and environmental monitoring. ePropelled positioned the line for commercial, industrial, military, and consumer UAV buyers.
Source - 2020-05-28 - Partnership - ePropelled signs UAV Propulsion Tech as distributor
The announcement targeted defence and commercial UAV customers. UAV Propulsion Tech was named as distributor for ePropelled electric motors. Nick Grewal said the distributor relationship would help ePropelled reach the UAV market.
