KDE Direct

Commercial drone componentsKDE Direct is a leading designer and manufacturer of high quality components for single- and multi-rotor unmanned aerial systems (UAS). We are a market leader in both custom and off-the-shelf brushless motors, electronic speed controllers (ESCs), and military-grade propeller blades for commercial and industrial drones.

Our components are used in a wide variety of professional UAS applications, from LiDAR scans and surveying to mapping of oil rigs and agricultural crops and enabling heavy lifting unmanned aircraft in aerial cinematography.

Our products are created with detailed design intent, finite-element analysis, and the strictest machining guidelines. We have been awarded the ISO 9001 certification for our production facilities, and our products are RoHS (The Restriction of Hazardous Substances), CE (European Conformity), and WEEE (The Waste Electrical and Electronic Equipment Directive) compliant for commercial and industrial applications.

Heavy Lift UAS Brushless Motors

Drone with Brushless Motors
Our Multi-Rotor Brushless Motors are aerospace-grade products designed specially for heavy-lift commercial and industrial UAS applications. Featuring a high-efficiency 28-pole design and triple-supported, ABEC-7 angular-contact and radial bearings for high-thrust capacity and extreme durability, the motors have been engineered to provide the best possible performance for a wide range of unmanned flight needs.

The motors also incorporate high-temperature (240°C continuous, 340°C maximum) solid-core copper windings, 0.2mm silicon-steel stator laminations and Kevlar tie-wraps, and an integrated centrifugal fan for cool running temperatures and sustained performance in even the most extreme of conditions.

Multi-Rotor UAS Electronic Speed Controllers (ESC)

UAS Electronic Speed ControllersOptimized for use with the UAS Multi-Rotor Brushless Motor Series, our plug-and-play Electronic Speed Controllers facilitate the next level of performance and efficiency for your unmanned aircraft applications. The Electronic Speed Controllers are housed in a rugged aluminium case and are sealed for all-weather operation, allowing them to be utilised in harsh environments.

Our UAS ECS also include active anti-spark circuitry, protecting the critical connectors upon each initial plug-in and system power-up and prolonging the system’s lifespan.

The pre-loaded production firmware enables an array of essential technologies for UAS flight applications:

Regenerative Braking – active braking during the motor deceleration phase, providing instantaneous response to the flight controller commands and matched-response to acceleration profiles, resulting in less “float” during flight

Temperature-Controlled Synchronous Rectification – our new proprietary algorithm enables smooth-running motors at low-throttle and improved, faster response under high-peak loads, all while significantly increasing flight-time efficiency and reducing operating temperatures

Dynamic Timing and Startup Power – optimally-tuned for smooth and precision-controlled startup, with no hesitation, stuttering, or response lag

Increased Drive and Throttle Frequency Resolution – high-accuracy, linear throttle response throughout full range of operation control

Motor Synchronization – factory-calibrated for consistent throttle control and frequency-matched start-up protocols
