Overview
The GEPRC EM3215 Motor Series is designed for 9–10 inch long-range FPV drones, offering high torque, strong structural durability, and efficient power delivery. Available in 900KV and 750KV variants, this motor is optimized for 6S LiPo (25.2V) setups, supporting different propeller sizes and flight profiles—from agile mid-range to payload-capable endurance builds.
Featuring a robust M5 steel shaft, N52H magnets, and NMB bearings, the EM3215 ensures smooth rotation, low vibration, and long-lasting performance. The 900KV model excels in thrust-to-weight performance with lighter props, while the 750KV version is built for high-efficiency heavy-lift applications with 10-inch blades.
Performance Comparison (Tested on 6S)
| Model | Prop | Max Thrust | Max Power | Max Current | Max Efficiency | Temp (°C) |
|---|---|---|---|---|---|---|
| EM3215 900KV | HQProp 9x4.5x3 | 3383.9g | 1217.3W | 51.42A | 7.26 g/W | 89°C |
| EM3215 900KV | GF1050x3 | 4120.7g | 1739.5W | 73.9A | 6.17 g/W | 101°C |
| EM3215 750KV | Gefan 10x5x3 | 3985.6g | 1429.5W | 60.50A | 6.43 g/W | 85°C |
🔍 Note: GF1050x3 + 900KV combination offers the highest thrust, while 750KV performs with better thermal margin and smoother current curves.
