Product overview
The GEPRC EM3215 900KV/750KV Motor is a propulsion component for long-range FPV aircraft. Its construction combines a high-strength M5 steel shaft, N52H magnets, NMB bearings and a 12N14P configuration, with a magnetic circuit designed for high torque. Both variants measure φ38.6mm × 30.7mm and weigh 122g including wire. Their mechanical interface has a 19mm × 19mm mounting hole pattern and a φ5mm shaft with a protruding length of 17.2mm. Each motor has a 300mm, 18AWG lead.
The 900KV version specifies 9–10-inch propellers and long-range FPV models, with maximum power of 1780W, peak current of 75A and interphase resistance of 33mΩ. The 750KV version specifies 10-inch propellers and long-range FPV models, 1450W maximum power, 61A peak current and 43mΩ resistance. Copper windings are single-strand for 900KV and multiple-strand for 750KV. Both specify 25.2V input from a 6S LiPo and a 60A–80A ESC. The package contains one motor, four M3*8 round-head screws and one M5 anti-slip nut.
