High Power, High Reliability, Brushless Motor Control for UAV Power Systems

Currawong Engineering’s line of Velocity Electronic Speed Controllers (ESCs) provides high power, high reliability brushless motor control for UAV power systems. This product fulfils the pressing need for an aerospace grade electronic speed controller (ESC) for use with 3-phase brushless DC motors. Currawong has engineered a robust device with a high level of documentation, testing and traceability.

With peak output power in excess of 20kW, the Velocity ESC supports extreme heavy-lift applications. High voltage operation (up to 18S / 75V) reduces current losses and allows larger motors to operate more efficiently.

Currawong’s Velocity ESC is being used by many major players in the heavy lift UAV sector. The ESC is not subject to ITAR restrictions.

High speed glitch-free control is provided with the fully-isolated CAN interface, which also provides high-speed real-time telemetry data. In addition to monitoring RPM, current, voltage and temperature data, the ESC reports internal health monitoring statistics.

Extremely low impedance MOSFET switches with impedance matched drive circuitry means that the Velocity ESC runs cool, operating at partial throttle or maximum load. Reduced cooling requirements means easier airframe integration and increased flight endurance.

Currawong also offers a complete in-house ESC and motor optimisation service to configure your Currawong ESCs to your particular motor and individual requirements. Visit the Currawong website for more information and a free sample report.
