What motor to use for ground models: Popular technologies and selection guide
Recently, with the rapid development of drones, robots and intelligent ground models, motor selection has become a hot topic in the industry. This article will combine the popular discussions on the entire network in the past 10 days, analyze the motor types, performance comparisons and applicable scenarios commonly used in ground models, and provide structured data for readers' reference.
1. Inventory of popular motor types
According to recent technology forum and e-commerce platform data, the following three types of motors are the most widely used in ground models:
| Motor type | Proportion (volume of discussions in the past 10 days) | Core advantages |
|---|---|---|
| Brushless DC Motor (BLDC) | 42% | High efficiency, long life, low noise |
| Brushed DC motor | 35% | Low cost and simple control |
| stepper motor | 23% | Precise positioning, high torque |
2. Comparison of performance parameters
The following is a comparison of actual measured data of popular motor models (data source: recent technology media reviews):
| Model | Type | Rated power (W) | Speed (RPM) | efficiency | Reference price (yuan) |
|---|---|---|---|---|---|
| DJI 2312E | Brushless | 150 | 8000 | 85% | 320 |
| RS-540SH | There is brush | 80 | 12000 | 70% | 65 |
| NEMA 17 | step by step | 50 | variable | 75% | 180 |
3. Analysis of applicable scenarios
According to recent industry reports and user feedback, the best application scenarios for different motors are as follows:
| Application scenarios | Recommended motor type | Reason |
|---|---|---|
| Racing ground model | High speed brushless motor | Strong explosive power and good heat dissipation |
| Education/Entry Level Model | brushed motor | Low cost and easy maintenance |
| Precision control robot | Closed loop stepper motor | Accurate positioning and anti-interference |
4. Suggestions on purchasing
1.Budget first: Students or beginners can choose a brush motor set (recently, the promotional price on e-commerce platforms is generally less than 200 yuan).
2.Performance first: Professional players recommend choosing brushless motors. Recently, new motors from DJI, Hobbywing and other brands support intelligent speed adjustment functions.
3.special needs: For scenarios that require position control (such as robotic arm models), a stepper motor system with an encoder is recommended.
5. Observation of Industry Trends
Popular discussions in the technology community in the past 10 days show:
-Integrated design: New motors begin to integrate drive circuits and sensors (such as temperature detection).
-Energy efficiency upgrade: The efficiency of the third-generation silicon carbide (SiC) material motor has been increased to more than 90%.
-Intelligent control: Distributed motor control systems based on CAN bus have become a research hotspot.
From the above analysis, it can be seen that the selection of ground model motors needs to comprehensively consider performance, cost and scene requirements. It is recommended that users refer to the latest evaluation data before purchasing, and pay attention to the matching of the motor, controller, and battery.
