What kind of motor is used for the 2-inch paddle of the traversing machine: hot topics and purchasing guide on the Internet
Recently, the community of traversing machine enthusiasts has launched a heated discussion around "matching 2-inch propeller motors". This article will combine hot topics and actual measurement data from the entire network in the past 10 days to provide players with a structured purchasing guide.
1. Comparison table of core parameters of 2-inch propeller motor
| Motor model | KV value | Recommended battery | Thrust (g) | Weight(g) |
|---|---|---|---|---|
| EMAX 0802 | 19000KV | 1S | 120 | 3.2 |
| Happymodel EX0802 | 25000KV | 1S-2S | 150 | 3.5 |
| T-Motor F0802 | 16000KV | 2S | 180 | 4.1 |
2. Analysis of hot discussion points
1.KV value controversy: The actual measurement of the "FPV veteran driver" of the UP station B shows that the 16000-20000KV motor efficiency of the 2-inch propeller is the best when using the 2S battery, and serious heat will occur if it exceeds 25000KV.
2.weight balance: Voting from overseas forum RC Groups shows that 75% of players choose a 3.5-4g motor paired with a 2-inch 3-blade propeller to achieve the best thrust-to-weight ratio.
3.New product news: The 0803 motor (4.2g/22000KV) released by iFlight last week has become a new hot topic, and its ceramic bearing design has attracted attention.
3. Comparison of typical configuration solutions
| scene | Motor combination | Battery life | Suitable models |
|---|---|---|---|
| Indoor flower fly | 0802+19000KV | 4-5 minutes | 65mm wheelbase |
| racing practice | EX0802+22000KV | 3-4 minutes | 75mm wheelbase |
| Outdoor shooting | F0802+16000KV | 6-8 minutes | 85mm wheelbase |
4. Suggestions on purchasing
1.1S system: Priority is given to 19000-22000KV motors with 31mm propellers. Note that the ESC must support high-speed PWM signals.
2.2S system: It is recommended to use a 16000-18000KV motor with Gemfan 2024 three-blade propeller to reduce current consumption by 10%.
3.Modification tips: Actual measurements by Tieba users show that replacing N52 magnets can increase the thrust of the 0802 motor by about 15%, but attention must be paid to the dynamic balance of the rotor.
5. Forecast of future trends
According to DroneRacing101 community research, the next generation of 2-inch propeller motors will show three major trends:
1. Increase the proportion of coreless motors to 40%
2. Standard bidirectional Dshot protocol
3. The average weight drops below 3g
Players are advised to pay attention to T-Motor’s upcoming 0801SE series (expected to be launched in August), which claims a thrust of up to 200g @ 3.8g weight.
