Drone motor design and manufacturing related

Unmanned aerial vehicle, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft operated by radio remote control equipment and its own program control device, or is operated completely or intermittently autonomously by an on-board computer. Compared with manned aircraft, drones are often more suitable for high-risk and difficult tasks. UAVs can be divided into military and civilian uses according to their application fields. In terms of military use, UAVs are divided into reconnaissance aircraft and target drones. Civilian applications in aerial photography, agriculture, plant protection, micro-selfies, express transportation, disaster relief, observing wild animals, monitoring infectious diseases, surveying and mapping, news reporting, power inspections, disaster relief, film and television shooting, creating romance, etc., greatly Expanding the uses of drones themselves, developed countries are also actively expanding industry applications and developing drone technology.

The design method of drone motor mainly involves the following aspects:

1. Motor type selection: 

There are generally two types of drone motors: brushless DC motors and brushed DC motors. Brushless DC motors are widely used in the field of drones because of their advantages such as high efficiency, low noise, long life, and low maintenance costs. The advantage of brushed DC motors is their low cost, but they are gradually being phased out due to their vulnerability to damage and low efficiency.

2. Winding structure: 

The structure of the motor winding directly determines the efficiency of the motor. A good winding structure can reduce the resistance when current is conducted and improve motor efficiency. The drone motor will generate a lot of heat when running at high speed. If the heat cannot be dissipated in time, the life and performance of the motor will be affected. Therefore, some heat dissipation measures need to be taken, such as installing heat sinks and adding heat dissipation holes. At the same time, choosing a high-quality motor can also improve the heat dissipation effect. When producing brushless motors for drones, the winding process is very important. If the winding effect is not good, it will directly affect the use of the drone. NIDE drone motor outer rotor winding machine adopts automatic winding machine technology to meet the needs of winding multiple motor products at the same time, with high efficiency and high precision.

3. Motor materials:

Choosing high-quality materials can minimize motor energy loss and extend the service life of the motor. When selecting materials, it is necessary to evaluate the material's heat resistance, flame retardancy, and wear resistance to ensure that the motor can operate normally in different climates and situations.

4. Size and weight: 

In order to reduce the total weight of the drone and increase the power density, it is necessary to design an efficient motor in the smallest possible volume. Therefore, when designing a motor, there is a need to balance motor size and weight with efficiency. In addition, the size and weight of the motor also have a certain impact on the stability and flexibility of the drone during flight.

5. Speed controller: 

The speed controller of the motor can reduce energy loss and improve the efficiency of the motor. Currently, high-precision adaptive control and proportional-integral-derivative control are two commonly used speed controller design methods.

In short, 

UAV motor design requires multiple aspects to be considered and comprehensively measured to find the optimal solution and achieve efficient performance and stable operation. Therefore, motor designers need to comprehensively consider factors such as UAV usage requirements, environmental conditions, materials and process control, and continuously improve and innovate.
