GateKEEPER
GateKEEPER is a unified technology platform that underpins the next generation of motor controllers.
Key features include:
- A proven motor control IP core
- Robust performance and high reliability that Hargrave Technologies is known for on any integrated inverter
- Bespoke controllers can now be derived from the same flight-tested platform as our COTS offerings
- New generation of wide-bandgap technologies, supporting bridges based on Silicon Carbide and Gallium Nitride
FOCAL
Hargrave Technologies' FOCAL algorithm sets a new standard for sensorless motor drive, optimised for the most demanding UAS applications. FOCAL extends the low-speed efficiency of FOC to the high-RPM performance of trapezoidal drive, with no tuning required.
While FOC can see higher peak efficiencies in a perfectly tuned combination, this is rarely true in real-world missions. Diverse flight profiles, environmental conditions and production variations all reduce the practical efficiency of FOC.
FOCAL has been developed to bridge the gap, constantly adapting to provide industry-leading transient response and optimised efficiency and acoustic signature.
We offer turn-key electrical design services, including certification, utilising uniquely developed in-house IP.
Our product lines deliver high-quality and reliability suited to defence and commercial applications. We operate on-site manufacturing facilities, including a comprehensive SMT production line, which ensures complete control over every stage of production.
