What to pair it with

Our reading of GEPRC’s numbers, so your build matches what the motor was tested with.

ESC

GEPRC lists a 12 A ESC for the 3000KV and 20 A for the 4600KV. Its tables peak at 9.92 A (3000KV, 16 V) and 14.3 A (4600KV, 12 V). (GEPRC spec image, GEPRC datasheet)

Props

3 to 4-inch for the 3000KV, which GEPRC tested on an Avan Scimitar 3.5×2.8×3 and a Nazgul 4030 (the 4030 pulled more); 2 to 3-inch for the 4600KV, tested on HQ T3×3×3, HQ Durable Prop T3×3 and HQ T2×2.5×3. (GEPRC spec image, GEPRC datasheet)

Battery

4S for the 3000KV, 3S–4S for the 4600KV. (GEPRC spec image)

Frame

Four M2 holes on a 9 × 9 mm pattern; GEPRC says it suits 2 to 4-inch lightweight frames. (GEPRC product page, GEPRC drawing)

Bench data

Redrawn from GEPRC’s test reports. Thrust is static pull on a bench, more than you get in flight. Power is volts × amps; efficiency is thrust divided by power.

Inside the motor

A brushless outrunner: the coils stand still in the middle and the magnets spin around them. From the top down:

• Bell. Black with red cut edges, over N52H magnets. (GEPRC product page, GEPRC spec image)
• Stator. 9N12P, wound with single-strand copper wire. (GEPRC product page, GEPRC spec image)
• Bearings. NMB/NSK bearings, which GEPRC says resist wear. (GEPRC product page, GEPRC spec image)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 3000KV version reaches about these speeds; a prop loads the motor and brings it down, typically to around 70–75% of these figures at full throttle.

A 12-pole rotor has 6 pole pairs, so every turn of the shaft is 6 electrical cycles, and a six-step ESC switches the phases 36 times per turn.

About the 3D model

A generic outrunner drawn from GEPRC’s published sizes: the 14 × 4 mm stator, 18.2 mm bell, 13.8 mm height, 1.5 mm shaft, 9 mm mounting circle and 9 teeth and 12 magnets. Anything GEPRC doesn’t publish is typical for a motor this size, and the bell’s spoked top, the base and the inside are a generic design, not this motor’s. The colours are read off the maker’s product photos. There are no logos or markings: it is our drawing, not the maker’s.
