A starter generator has sufficient torque and power to start the engine from the onboard battery power. ePropelled’s Starter Generators can also be used as a propulsion motor that uses the energy stored in the battery in a hybrid application.
Technically, these are different electrical machines performing a similar function in supplying electrical power. If the electrical machine is only used to generate power for the onboard systems, it may be referred to as an alternator. A starter generator differs from an alternator in that it has sufficient torque and power to also start the engine from the onboard battery power. ePropelled’s Starter Generators can also be used as a propulsion motor that uses the energy stored in the battery in a hybrid application.
ePropelled’s starter generators and power systems for UAVs are designed for commercial, defense, security, and other tactical applications. They are not designed for consumer UAVs typically used for aerial photography.
The mission profile of the UAV determines the payload and operating parameters which subsequently determines other factors such as propulsion method and electrical power requirements. These decisions should not be made in isolation. There are ways to design in synergies between the propulsion system and the power system to create a lighter and more efficient aircraft. We can help you determine the best possible solutions for your aircraft.
The rotating part of an electrical machine such as a generator, motor, or alternator.
The stationary part of an alternator in which another part (the rotor) revolves. The stator contains the conductor where the electric motive force (EMF) is induced (generally the conductor is in the form of a coiled wire called windings).
Windings are the wire used as a conductor that is wound on the stator armatures.
A device that uses active rectification and regulation to supply outputs of one or more DC voltages from the variable AC input. Different onboard systems require different DC voltages. For example, the payload may use 12 volts while the avionics may use 5 volts. Also known as a Power Management Unit.
No, different companies call them by different names. ePropelled’s power systems are called “Intelligent” Power Systems due to the software built into the system. Real-time data monitoring and system alerts make these units smarter than the average power management unit.
A Controller Area Network (CAN) is a serial network technology that was originally designed for the automotive industry but has also become a popular bus in industrial automation as well as other applications. The CAN is a bus-based system that can be used in embedded systems to provide fast communication among microcontrollers in intelligent devices without the help of a hosting device. CAN is an International Standardization Organization (ISO) defined serial communications bus. It is a message-based protocol allowing individual systems, devices, and controllers within a network to communicate.
