Understanding Drone Battery Life 1

Technology has improved drone engines, and the power train is UAV models. This is a great advantage because you can perform longer flights with better precision. Also, the higher the engines’ quality, the longer they last and the quieter they are when flying.

The vital components of drones are motors, propellers, and electronic speed controls. From now on, you will know how drone engines work, and you will have access to very interesting videos of the operation of propulsion systems.
The propulsion system design has several parts.


The engine has some main components:

– Wired
– Motorcycle stator
– Engine hood
– propeller
– Electric speed controllers
– Aspects
– ESC Updater
– Windings
– Arm
– Refrigeration system

Drone Engine Operation

The Drone Motor Stator

This part is stationary and is in electric motors. This system generates the rotating magnetic field formed by the stator core, the stator frame, and the stator winding.

The Motor Bell Drone

The part of the motor that rotates on the drone belongs to the motor bell. In a quadcopter drone, four motors are divided into two clockwise and two counter clockwise. But this is done through configuration.

Air Gaps

Between the rotor bell and the stator, there is a distance called between iron. This is the air space, and when the drone is armed, this space is as small as possible. If the air gap is wide, the drone will not perform well.

Drone Motor Windings

In the bovines are the windings of the electric motors that are of copper wires. These windings are wrapped in a magnetic core of soft iron material, and in this way, the magnetic poles are formed.

How Is The Repair Of A Motor And Windings?

These are the reasons why:

– Incorrect drone flight
– The motor does not work
– The motor does not rotate
– The windings have broken
– It has a strange sound
– The engine jumps
– There is a delay in the motor response

Drone Motor Bearing Performance

This process turns out to be very simple, and its main function is to locate the rotor and transfer the loads generated by the shaft to the motor. Also, it is in charge of keeping the air space reduced and of operating at low or high speeds depending on the situation. When there are bearing failures, you can see it immediately in the drone’s engine.

Drone Motor Design

Drone motor designs are lightweight but strong so that they provide the highest efficiency. The idea is that the motor has a quality performance while using a little battery. The efficiency of the drone will always depend on the efficiency of the motor.
The motors also are capable of withstanding any type of weather.

The Operation Of The Drone Cooling System

Excessive heat buildup on the drone’s engine can damage it. That is why it is so important for drones to have a cooling system. The cooling system in most drones is centrifuged while, for example, that of airplanes is an integrated centrifuge.

The Drone Engine Needs Protection

A drone needs to have the motor and strong components to be able to withstand any weather conditions. Motors must also be kept protected from dust particles and corrosion. For this reason, drone engines are sealed to cover the bearing system fully.

Protection Of Drone Components

Each drone motor has an IP code to qualify and classify the degree of protection that the motor has. This will vary according to the electrical cabinets and metal housings that the drone has. The idea is to keep the components protected from water, western contact, and dust.

Electric Drone Speed Controllers

Electric controllers are a circuit that controls the acceleration and deceleration of drones. Apart from having electric safety controllers, the latest generation drones also have FOC algorithms for greater precision of motor control.

ESC Wiring And Drone Motor

– This is the configuration of the wiring of this system:
– ESC and motor cables: 3 cables of various colors
– ESC cables from the power connector: 1 red and one black
– Motor cables and ESC cables: 3 cables, one red, one yellow and the other black
– ESC connector to flight controller: 1 white wire and one black wire

The Esc Updater

When you purchase a state-of-the-art drone, the manufacturer will release constant software updates to detect and repair any errors that are detected quickly.

ESC Operation

In the videos that this site shows you, you can see how ESC works.
High Technology In Electric Speed Controllers
The latest drones have a variety of smart functions, and you can find two types of electric speed controllers on the market:
1- DJI Takyon Z14120 ESC
This model features two single-core 32-bit processors to display efficient real-time monitoring.

ESC Monitoring

This monitoring will prevent the drone from surpassing current and overheating. This option will keep the drone protected to reduce maintenance costs.

Esc Heat Decrease

Thanks to this option, the latest technology drones have this system so that drones with high power can operate for a full day without fans’ use.


These are the characteristics of the KDE-UAS125UVC-HE ESC model:
– It has a high memory for better data recording.
– How much with feedback through the KDECAN.
– It has regenerative braking.
– Synchronous ratification controls The algorithm i.
– Active monitor, thanks to hardware.
– Synchronization of the engine.
– Circuit anticipates for the protection of connectors.

Drone Arm

In the arm of the drone, there is wiring that goes from the mainboard that is in the controller to the ESC. This arm is part of the drone quadcopter.

The Operation Of The Drone Propellers

When the drone is advancing, the propellers are pushing backward; it is Newton’s third law of motion procedure.

Drone Motor Propeller Design

Propeller propellers push the drone forward when they send a mass of air behind the drone.

Drone Propeller strength

The DJI E7000 powertrain uses quality propellers for added strength and comes in various sizes and models to suit every drone.

Angled Propellers

They are adjusted to the angle to provide a better inclination, and this is what will determine the speed in which the drone can move.

How Does A Quadcopter Motor Rotate?

The quadcopters have four engines, and together with the propulsion system, they are responsible for providing speed to the equipment.

Vertical Plane

A quadcopter in the vertical plane can:
– scroll
– Go up
– Go down

Drone Propulsion System

Quadcopters can rotate freely in the following dimensions:
– Tone
– Roll
– yaw

How To Buy Drone Engines And Propulsion Systems?

Manufacturers recommend purchasing complete powertrains as they come with propellers, engines, and ESC.

Better Engines

– Motor T
– Lumenier
– iFlight
Each of these engines has important characteristics that will provide greater resistance to the drone.
