2–3-inch toothpick motor
T-Motor M1103
A 4.6 g one-piece-bell micro motor with N52 arc magnets and NMB bearings, for 1.6–2.5-inch whoops and 2–3-inch toothpicks: 8000KV for 2S–4S, 11000KV for 2S–3S.
- 1.6–2.5-inch whoops
- 2–3-inch toothpicks
- 2S–3S (both KVs), 4S (8000KV)
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1103 motor drawn from T-Motor’s published sizes, not its exact design. Thrust, current and power are T-Motor’s bench figures for the GF2015-2 prop at 16.8 V, read straight across between its throttle steps. Its data starts at 20% throttle.

What it pulls
T-Motor’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.
At 60% with the GF2015-2: 154 g of thrust, 5.9 A, 99 W, 1.56 g per watt.
On your quad
1.4 : 1
Thrust to weight at full throttle: four motors pull 901 g with the GF2015-2 at 16.8 V.
At 60% throttle they pull 616 g, 0.9 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 you get for $11.90
4.6 g
4.64 g with leads for the 8000KV, 4.61 g for the 11000KV.

Bench data
Redrawn from T-Motor’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. One piece, 14.5 mm across, blue with silver machined edges, with four M2 holes on a 5 mm circle round the shaft in the top. (T-Motor drawing, specs and test report)
- Shaft. 1.5 mm, standing 2.85 mm above the bell, stepped inside so it cannot pull out. (T-Hobby product page)
- Bearings and magnets. NMB 502ZZ bearings; N52 arc magnets forming 12 poles round a 9-slot stator. (T-Hobby product page)
- Base. Four M2 holes, opposite holes 9 mm apart; three 24 AWG leads, 75 mm long. (T-Motor drawing, specs and test report)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 8000KV 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 | 118,400 | 11,840 Hz | 71,040 |
| 4S full | 16.8 | 134,400 | 13,440 Hz | 80,640 |
| 6S nominal | 22.2 | 177,600 | 17,760 Hz | 106,560 |
| 6S full | 25.2 | 201,600 | 20,160 Hz | 120,960 |
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 T-Motor’s published sizes: the 11 × 3 mm stator, 14.5 mm bell, 10.7 mm height, 1.5 mm shaft, 9 mm mounting circle and 9 teeth and 12 magnets. Anything T-Motor 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.
