Our Technology

At the heart of our technology is GateKEEPER, a unified technology platform that underpins the next generation of drone motor controllers.

Key features include:

• Proven motor control architecture with advanced proprietary algorithms, combining the low-speed efficiency of FOC with the high-speed performance of trapezoidal drive
• 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
• Supports a new generation of wide bandgap semiconductor technologies including Silicon Carbide and Gallium Nitride bridges
• Compatible with any flight controller that supports DroneCAN, PWM or Dshot

Drone Motor Controllers & Drone ESCs

microDRIVE LP

Compact and lightweight IP67-rated ESC for drone motor control

microDRIVE LP is our smallest and lightest drone motor controller, designed from the ground up around the DroneCAN specification for easy integration into UAV platforms and deployment at scale. The versatile ESC enables you to choose between our groundbreaking high-efficiency FOCAL or rapid-response trapezoidal drive algorithms, allowing you to tailor the solution to your specific needs.

Users can configure over 60 parameters and update firmware from the flight computer. Real-time telemetry allows you to monitor and capture critical data such as current, voltage and RPM, ensuring that issues can be spotted before serious problems occur. microDRIVE LP also provides a host of other advanced features including error-correcting memory, onboard diagnostics, and high-speed circular data logging with storage for up to 72 hours.

The rugged motor controller is IP67-rated for operation in harsh environments, and can be optionally provided as a fully NDAA-compliant product for U.S. government and defense applications.
