High-Reliability BLDC Drone Motor Controllers & Electronic Speed Controllers (ESCs) for UAVs

XC-ESC is a specialist developer and manufacturer of electronic speed controllers (ESCs) for UAVs (unmanned aerial vehicles) and unmanned systems.

Our high-reliability BLDC drone motor controllers have been provided to a wide range of clients in over 30 countries, powering a variety of different applications including cargo delivery, firefighting and emergency response, inspection and surveying, and UAM (urban air mobility).

We undertake all design, manufacturing and testing in-house in our state-of-the-art NQA-accredited facilities, ensuring that we maintain the utmost in quality standards. We also provide professional expert R&D and product design services for custom applications, allowing us to provide bespoke solutions that meet unique customer requirements with fast turnaround times.

ESCs for Drones

Our advanced ESCs are compatible with many popular drone motors currently available on the market, and provide a comprehensive suite of features that make them an ideal choice for a wide range of drone and robotics designs.

Rapid response – our cutting-edge motor control algorithm delivers excellent response times, and ensures that units require no additional timing adjustments or calibration

Low-temperature design – our motor control software significantly reduces the heat generated during startup, operation and shutdown, and sophisticated structural design with copper conduction provides maximal temperature dissipation

Automatic energy recovery – thanks to improved throttle linearity and regenerative braking, our ESCs feature enhanced efficiency and the ability to convert recovered mechanical energy into electrical energy

Advanced safety features – our highly reliable ESCs provide multiple built-in protective features including over-voltage, over-temperature, stall and throttle signal loss protection, and infinite restart. Control signal interfaces are isolated from the main power supply for enhanced safety and reliability.

CAN communications – provides real-time communications with the drone flight controller, and enables monitoring of a variety of ESC and motor parameters including throttle values, voltage, current, motor speed and temperature. Firmware can be upgraded easily via CAN, and all units are compatible with the CyphalCAN and DroneCAN protocols.

All our motor controllers are IP67-rated for maximum longevity and reliability under highly challenging operating conditions.
