DJI – Drones

DJI Overview

DJI specializes in the Drone industry. They provide a large range of Drones for users, including basic drones for recreational flying, and the more advanced ones which are typically attached with cameras or sensors for commercial uses. DJI provides both the hardware and the software solutions to its clients, while also providing additional drone accessories to enhance the flying experience.

DJI Introduction & History

大疆 (Dà-Jiāng) Innovations, more commonly known as DJI, is a relatively new Chinese technology company started in 2006.  They specialize in the drone industry and with manufacturing facilities throughout the world, have made significant breakthroughs in many drone related technology. Such technology include camera gimbals, flight platforms, cameras, propulsion systems, camera stabilizers, and flight control systems.

DJI Electronic Speed Controllers (ESC)

The ESC is an electronic circuit that serves the purpose of varying the speed of the electric motor. This essentially controls the speed, direction and brake systems of the drone via its motors. ESC are essential in almost every drone and required high amount of power, frequency and AC power, often compacted into a miniature package.

A massive leap in ESC innovation came on the DJI Inspire 1, which uses new sinusoidal drive ESC to replace the squarer wave drive of traditional ESCs. The Inspire 1 goes further by using closed loop torque control and distinct functional redundancy, which adds extra efficiency and reliability to the motors.
