Defense & Aerospace Application

UAVs have long been used for defense reasons, including providing superior intelligence, surveillance and reconnaissance (ISR). With defense applications requiring low-noise propulsion systems comprised of fuel-to-electricity and electricity-to-thrust systems, Calnetix Technologies’ Magnaforce™ high-speed motor generator systems provide light-weight turbo alternators for airborne power generation and high-power densities for electric thrust. Calnetix motor generators eliminate the need for bulky gearboxes used to mechanically couple the UAV’s drive train system. The resulting reduction in weight extends operational endurance and payload capabilities, while also reducing detection by decreasing the range of sound generated by the UAV. Additionally, if the UAV has an energy storage unit, the electric propulsion capability generates additional power allowing for the UAV to perform critical missions, such as C5ISR (Command, Control, Communications, Computers, Combat Systems, Intelligence, Surveillance and Reconnaissance).

UUVs (Unmanned Underwater Vehicles) have performed significant missions in the Navy and these functions have regularly been incorporated into Department of Defense (DOD) and Ministry of Defense (MOD) tactics, techniques and procedures. These defense applications include intelligence gathering, maritime reconnaissance, undersea surveillance and communications. While UUVs vary in sizes, space and weight are always priority considerations on all platforms. UUV payloads require high-power density motor generators that will ensure long periods of operation at sea. Calnetix Technologies’ Magnaforce™ permanent magnet motor generators provide the best combination of size, power, cost and reliability. Magnaforce™ motor generators are customizable for special applications and provide excellent energy efficiency, minimal footprint and low maintenance cost savings.

Although USVs (Unmanned Surface Vehicles) do not have the same historical usage in defense applications compared to UUVs, the Navy has increasingly been looking at new opportunities where USVs can be utilized. As the Navy creates the Seabed to Space Communications Network, power density needs for all domains Undersea, Sea Surface, Land, Air, and Space will continue to increase. Calnetix Technologies’ Magnaforce™ permanent magnet (PM) motor generators and Powerflux™ magnetic bearings fulfill these power density needs and present designers with the flexibility for their unique applications.

UGVs (Unmanned Ground Vehicles) are slowly becoming a part of defense arsenals with the increase in demand for reliable and efficient defense applications on land. Seen as a safer alternative to conducting Land Warrior intelligence, surveillance and reconnaissance (ISR) missions, UGVs reduce the risk of personnel casualties and enable more accurate combat targeting.  Many of the advantages and applications facilitated by Magnaforce™ permanent magnet (PM) motor generators, Powerflux™ magnetic bearings and Vericycle™ variable speed drives also apply to UGVs.
