ePropelled is the leader in magnetic engineering innovations that dramatically improve electric motor and generator efficiency for propulsion applications for aviation, aerospace and electric vehicles.

Gwynt is ePropelled’s complete line of starter generators, power management units, electric motors and motor controllers for UAV power and propulsion applications:

Motors and Controllers

ePropelled’s Gwynt Propulsion Motors build on our expertise in electrical machines, material science and magnetic engineering. Our brushless permanent magnetic motors start with a frameless pancake form factor. This allows us to be very efficient in space utilization while providing maximum flexibility in mounting options. Commercial UAV applications from delivery to security to transporting passengers, require UAVs to stay airborne for extended periods, carry larger payloads and minimize the noise level in operating areas. As a result, designers are looking to electric motors for UAV propulsion applications. These applications require compact, light, energy-efficient components that can contribute to a platform’s size, weight & power coefficient.

Starter Generators

ePropelled's Gwynt series are the most versatile starter generators in its category. Its slim line design boasts a patent pending active air cooling system that allows it to operate in temperatures in excess of 200°C in certain applications. Our unique patent pending adaptor allows bearing less mounting of the starter generator directly on to engines. The Gwynt outer rotor series boasts the lowest weight in its class with outstanding power density. Our starter generators can be customized to meet your exact application including low and very high power output options.

Power Management Uniits

Gwynt PMUs provide the highest level of flexibility to meet your exact requirements. We use a unique modular design and all secondary outputs are programmable. There is an optional Electronic Engine Starter (EES) function to use our starter generator to start an engine. Once the engine up to speed, the PMU delivers regulated voltages. If for any reason the starter generator stops working, a backup battery (optional) automatically comes online and provides the regulated voltages for a fixed duration depending on backup battery size. Our PMUs are designed to provide power over a wide RPM range. Units are lightweight, have forced air cooling and are highly efficient to minimize fuel consumption.
