What motor is used for six-axis aircraft?
Hexacopter, as a type of multi-rotor drone, is widely used in aerial photography, agricultural plant protection, logistics and transportation and other fields because of its stability and load capacity. The choice of motor is directly related to the performance, endurance and reliability of the aircraft. This article will combine the hot topics and hot content on the Internet in the past 10 days, analyze the key points of six-axis aircraft motor selection, and provide structured data for reference.
1. Core parameters of six-axis aircraft motor
When selecting a motor, focus on the following parameters:
| parameters | Description | Typical values (six axes) |
|---|---|---|
| KV value | Rotation speed per volt (RPM/V) | 200-500KV (medium and low speed models) |
| Power | Motor output power (W) | 300-800W (depending on load requirements) |
| Size | Stator width × height (mm) | 4110, 5010, etc. |
| weight | Single motor weight (g) | 80-200g |
2. Comparison of popular motor models (latest data in 2024)
According to the recent discussion in the drone community, the following models have attracted much attention:
| Brand | Model | KV value | Maximum power | Applicable propeller |
|---|---|---|---|---|
| T-Motor | MN501-S | 340KV | 600W | 18-20 inches |
| X4110S | 400KV | 480W | 15-17 inches | |
| DJI | 3510 | 480KV | 350W | 13-15 inches |
3. Key factors in motor selection
1.Load matching: The ratio of the total weight of the hexacopter (including battery and load) to the motor thrust is more than 1:2. For example, if the aircraft weight is 2kg, you need to choose a model with a single motor thrust ≥ 400g.
2.battery voltage: High voltage (6S-12S) systems are usually paired with low KV motors to improve energy efficiency. In recent hot discussions, 6S lithium battery with 300-400KV motor has become a mainstream solution.
3.Thermal design: The new motor adopts a hollow shaft design (such as the T-Motor Antigravity series), which improves heat dissipation efficiency by 30% and is suitable for long-term operations.
4. Industry trends and hot technologies
1.Brushless motor intelligence: The O3 image transmission system recently released by DJI requires motors to support adaptive adjustment of ESC parameters, prompting motor manufacturers to integrate more sensors.
2.Material innovation: Carbon fiber casing motors (such as Xing Carbon Edition) are 15% lighter and have become the new favorite of high-end models.
3.energy efficiency standards: The European Union plans to introduce an energy efficiency classification system for drone motors to encourage manufacturers to optimize electromagnetic design (see the hot discussion in the Reddit drone section for details).
5. Purchase suggestions
Recommended configurations based on application scenarios:
| scene | Motor type | Typical battery life | Budget (single motor) |
|---|---|---|---|
| aerial photography | Low KV brushless (300-400KV) | 25-35 minutes | ¥400-800 |
| Plant protection | High torque motor (200-300KV) | 15-25 minutes | ¥600-1200 |
| racing | High KV brushless (500-700KV) | 8-12 minutes | ¥200-500 |
Note: The above data combines the recent sales statistics and user reviews of Banggood, HobbyKing and other platforms.
Conclusion
The selection of motors for hexacopters requires comprehensive consideration of power requirements, energy efficiency ratio and cost control. Newly released motors in 2024 generally emphasize lightweight and intelligent control capabilities. It is recommended to give priority to models that support programmable parameters. Before actual purchase, be sure to refer to the thrust test data of the corresponding propeller (the FliteTest channel has a detailed evaluation video recently) to ensure system compatibility.
