1.6 to 2-inch 2S micro FPV motor

GEPRC SPEEDX2 1102

A 2.83 g 1102 for 1.6 to 2-inch 2S quads; on GEPRC’s 8 V bench it pulls 88 g at full throttle on a 51 mm four-blade prop, drawing 7.45 A.

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1102 motor drawn from GEPRC’s published sizes, not its exact design. Thrust, current and power are GEPRC’s bench figures for the HQ DT51-4B prop at 8 V, read straight across between its throttle steps. Its data starts at 30% throttle.

Max thrust: 88 g; HQ DT51-4B prop, 8 V
Weight: 2.83 g; with the leads
Peak current: 7.5 A; full throttle
Max power: 60 W; full throttle

What it pulls

GEPRC’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.

At 60% with the HQ DT51-4B: 55 g of thrust, 2.6 A, 21 W, 2.65 g per watt.

On your quad

All-up weight650 g

0.5 : 1

Thrust to weight at full throttle: four motors pull 352 g with the HQ DT51-4B at 8 V.

At 60% throttle they pull 220 g, 0.3 times the quad’s weight.

All-up weight is the quad ready to fly, with its battery and camera. The thrust is the maker’s static bench figure; in the air it is lower.

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. Its bench peaks at 7.45 A at full throttle on 8 V. (GEPRC product page, GEPRC datasheet)
Props: GEPRC lists the HQ DT51-4B, a 51 mm four-blade prop, and its datasheet is on that prop. (GEPRC spec image, GEPRC datasheet)
Battery: 2S (8.4 V). (GEPRC product page)
Frame: Three M1.4 holes on a 6.6 mm circle; GEPRC says it suits 1.6 to 2-inch lightweight models. (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:

Rotor. N52H magnets in a matte black bell with bright cut edges. (GEPRC product page)
Stator. 9N12P, wound with multi-strand copper wire. (GEPRC product page)
Bearings. NSK/NMB bearings. (GEPRC product page)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 10000KV 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.

Battery	Volts	No-load rpm (KV × V)	Electrical frequency	ESC steps per second
4S nominal	14.8	148,000	14,800 Hz	88,800
4S full	16.8	168,000	16,800 Hz	100,800
6S nominal	22.2	222,000	22,200 Hz	133,200
6S full	25.2	252,000	25,200 Hz	151,200

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 11 × 2 mm stator, 13.8 mm bell, 9.2 mm height, 1.5 mm shaft, 6.6 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.
