GEPRC EM3115 900KV Motor

The GEPRC EM3115 900KV is a large-stator brushless motor from the EM series, built for 8-inch to 10-inch long-range propellers on 6S platforms. Its high-torque magnetic circuit is designed to carry the payload of long-range cruisers and light cinelifters without overheating.

Key features

• 3115 stator with N52H magnets and a 12N14P winding configuration for strong low-end torque.
• High-strength M5 steel shaft with a 5mm diameter suits heavy-lift and long-range propellers.
• Handles up to 1620W peak and 65A peak current, matched to a 60-80A ESC.
• NSK/NMB bearings for durability under sustained load.
• 310mm 18AWG leads and a 19 x 19mm mounting pattern for straightforward installation.

At 900KV on 6S the EM3115 is tuned for cruising efficiency rather than raw speed, matching typical 8 to 10 inch long-range propellers rather than the smaller, higher-KV motors used on 5-inch freestyle builds.
