What kind of motor is used in a model aircraft? Comprehensive analysis of motor selection guide
The motor selection of a model aircraft is one of the key factors affecting flight performance. Different aircraft model types, sizes and flight needs have different requirements for motors. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the selection method of aircraft model motors and provide structured data for reference.
1. Types of model aircraft motors
Model aircraft motors are mainly divided into two categories: brush motors and brushless motors. As technology develops, brushless motors have become a mainstream choice, but brushed motors are still used in a small number of entry-level models.
| Motor type | Features | Applicable scenarios |
|---|---|---|
| brushed motor | Simple structure, low cost, but low efficiency and short life | Entry-level model aircraft, small toy airplanes |
| Brushless motor | High efficiency, long life, strong power, but higher cost | Intermediate and advanced aircraft models, FPV racing aircraft, large fixed wing |
2. Key parameters of brushless motor
The performance of brushless motors is mainly determined by parameters such as KV value, power, size and weight. The following is a comparison of recent popular model aircraft motor models and their parameters:
| Motor model | KV value | Maximum power(W) | Applicable models |
|---|---|---|---|
| T-Motor F60 Pro III | 1750KV | 650W | 5 inch FPV drone |
| EMAX ECO 2306 | 1900KV | 550W | 3-4 inch traversing machine |
| SunnySky X2212 | 980KV | 300W | Small and medium fixed wing |
3. How to choose the motor according to the type of aircraft model?
Different aircraft models have greatly different requirements for motors. The following are the recent popular model aircraft types and their recommended motor configurations:
| Model aircraft type | Recommended motor type | KV value range | Battery matching |
|---|---|---|---|
| FPV ride through machine | Brushless external rotor motor | 1700-2500KV | 4S-6S lithium battery |
| Fixed wing aircraft | Brushless inner rotor motor | 800-1500KV | 3S-4S lithium battery |
| miniature model aircraft | Brush/micro brushless | 5000-10000KV | 1S lithium battery |
4. Matching of motor and propeller
Motor selection also requires consideration of propeller size and load. The motor and propeller matching scheme that has been discussed most recently by aircraft model enthusiasts is as follows:
| Propeller size | Recommended KV value | Typical motor models |
|---|---|---|
| 5 inches (5045 paddle) | 1700-2200KV | T-Motor F60, EMAX ECO |
| 7 inches (7040 paddle) | 900-1300KV | SunnySky X2814 |
| 10 inches (1045 paddles) | 600-900KV | Hobbywing XRotor |
5. Recommended recent popular motor brands
According to the recent discussion in the aircraft model community, the following brands and models have attracted much attention:
| Brand | Popular models | Features |
|---|---|---|
| T-Motor | F60 Pro III | High power, low noise |
| EMAX | ECO 2306 | High cost performance |
| SunnySky | X2212 | Stable and durable |
6. Summary
Choosing a suitable model aircraft motor requires comprehensive consideration of factors such as model aircraft type, flight requirements, and propeller matching. Brushless motors have become mainstream due to their efficiency and durability, while brushed motors are still suitable for entry-level players. Recently popular motors such as T-Motor F60 Pro III and EMAX ECO 2306 are highly praised for their excellent performance. I hope the structured data in this article can help you find the right motor configuration quickly!
