ESC modules are important subsystems for non-military drones and users demanding more efficient models that provide longer flight times and higher dynamic behavior with smoother and more stable performance. This design implements an Electronic Speed Controller (ESC) commonly used for unmanned aerial vehicles (UAV) or drones.
The speed control is done sensorless, and the motor has been tested up to 1.2 kHz electrical frequency (12kRPM with a 6 pole pair motor), using FOC speed control. Our high-speed sensorless-FOC reference design for Drone ESCs provides best-in-class FOC algorithm implementation to achieve longer flight time, better dynamic performance and higher integration, resulting smaller board size and fewer BOM components. Sensorless high speed FOC control using TI’s FAST™ software observer leveraging InstaSPIN-Motion™ C2000™ LaunchPad and DRV8305 BoosterPack.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
