What is the general KV of the traversing machine motor?

As a racing and aerial photography tool that has rapidly emerged in recent years, the KV value of the motor, one of its core components, has become the focus of players' attention. The KV value directly affects the motor's speed, torque and adaptive battery voltage, and is a key parameter when selecting a motor. This article will combine the hot topics on the Internet in the past 10 days to conduct a structured analysis of the KV value range of the traversing machine motor and its application scenarios.

1. What is the KV value of the motor?

The KV value represents the rotation speed per minute (RPM) of the motor when the voltage is increased by 1V under no load. For example: a 2300KV motor rotates at 2300RPM at 1V voltage. If a 4S battery (16.8V fully charged) is used, the theoretical speed can reach 38,640RPM (load loss is not taken into account).

2. Popular motor KV trends in 2024

According to recent e-commerce platform sales data and forum discussions, mainstream configurations present the following characteristics:

3. The relationship between KV value and flight performance

Compare the performance differences of motors with different KV values through measured data:

4. Suggestions on purchasing

1.racing player: It is recommended to choose a 2200-2600KV motor, paired with a 4S battery and a high C-number ESC (such as 60A) to achieve instantaneous bursts.
2.Aerial photography users: It is recommended that 1800-2100KV motors be equipped with 6S batteries to balance battery life and stability.
3.Getting Started: You can choose a 2300KV general-purpose motor (such as EMAX Eco 2300KV), which is suitable for most standard sets.

5. Maintenance precautions

• High KV motors (>3000KV) require regular inspection of bearing wear
• A 20% margin should be left for matching ESCs (if a 2600KV motor requires a 35A ESC, choose a 50A model)
• It is necessary to clean up the metal debris in the gaps between the motor magnets after flight

To sum up, the selection of the KV value of the flying machine motor needs to comprehensively consider the model size, battery voltage and flight requirements. The current market mainstream is concentrated in the 1600-2600KV range. With the popularity of 6S batteries, the proportion of mid- to low-KV motors around 1800KV is gradually increasing. It is recommended that players refer to the latest measured data to avoid blind pursuit of high KV values, which may lead to unbalanced power systems.
