GEPRC EM3115 3115 900KV Long-Range Brushless Motor for 8–10 inch FPV Drones, 6S, 1620W, 5 mm Shaft

Overview

The GEPRC EM3115 3115 900KV is a high-efficiency long-range FPV motor built for 8–10-inch FPV drone platforms. It uses an N52H magnetic circuit for high torque, NSK/NMB bearings for smooth durability, and a 5 mm steel shaft. With a max output of 1620 W and peak current of 65 A on 6S (25.2 V), the EM3115 provides reliable thrust for long-range cruising and endurance builds. Standard 19×19 mm mounting and 310 mm 18-AWG leads simplify installation on 8–10-inch LR quads—including popular 10-inch FPV drone frames.

Key Features

• New EM series motor optimized for long-range FPV
