How to Calculate Drone Motor Thrust？
What is a BLDC Motor? A BLDC Motor that is brushless has no brushes, as the name suggests. The rotor and the stator are the two distinct parts that make up a brushless motor. BLDC Motor has revolutionized the world of electric motors, offering numerous advantages over their brushed motor. In this comprehensive guide, we will explore the principle of operation of brushless dc motors, highlighting their key features, benefits, and applications. Whether you are an enthusiast looking to build your own drone or someone interested in understanding the inner workings of these motors. What is BLDC Motor Thrust? Thrust is a reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction to be applied to that system. The force applied on a surface in a direction perpendicular or normal to the surface is also called thrust. A fixed-wing aircraft propulsion system generates forward thrust when air is pushed in the direction opposite to flight. This can be done by different means such as the spinning blades of a propeller, the propelling jet of a jet engine, or by… -
Do You Need Capacitors for FPV Drones?
Introduction What is a Capacitor for Drone? One of the most prevalent parts of an electronic system is a capacitor. Almost single electronic component used in our FPV drones, as well as practically all other electronic equipment, has many capacitors. Although capacitors exist in a wide variety of sizes and shapes, their capacitance to store charge generally increases with size. The most popular application of a capacitor is supply voltage smoothing. This type of application for a capacitor is known as decoupling. Similar to a small battery, a capacitor for drone may absorb and release electrical energy rapidly. It stores electric charge in an electric field between two conducting plates. To equal out voltage variations and shield other components from harm, the capacitor absorbs spikes in voltage and releases its stored energy when there is a drop in voltage. The Benefits of Extra Capacitors in FPV Drones In essence, the FETs in our ESC are switches. To power the motors, they rapidly switch on and off tens of thousands of times per second, which can produce a great deal of noise and electrical spikes. The issue gets worse as technology develops and makes stronger motors, ESCs, and greater battery voltages possible. It can make…

ESC Faults and Their Fixes: A Guide for FPV Pilots
ESC faults are one of the most common issues faced by FPV drone pilots. ESCs are common areas of fault, often receiving the most abuse and continued strain of any electronic in the RC object. In this guide, we will discuss common ESC faults and ESC troubleshooting, including ESC burnout, desync, and firmware corruption. For those looking to better understand ESCs and how to select the right one for their FPV drone, check out this comprehensive guide on How to Choose the drone ESC. Fault 1: Understanding ESC Burnout and Prevention Tips This is by far the most common issue experienced with ESCs. Most of the time ESCs are bulletproof and connected to the FC, which allows for minimal tampering on the firmware side of things, allowing for low anomalies in the typical use cases. Unfortunately, they are not indestructible and thus large crashes, excessive stress or overvoltage may occur. This is physical damage to the ESC and is unfortunately very rarely fixable and when it is, it requires micro soldering skills to replace the damaged component, writing it off as its never worth it unless the part is discontinued and essential. Some physical cues of this problem would be: Physical chips or cracks in the board. Black soot near pads and components indicating a burnt board. Missing components and empty micro pads. Other forms of internal damage that may not be visible. There are currently no real fixes to this issue and if you rule out…...
