1.6–2-inch toothpick and whoop motor
T-Motor M1104
A 5.6 g one-piece-bell micro motor for 2-inch toothpicks and 90–110 mm whoops, with N52 arc magnets and NMB bearings, in one 7500KV winding; it pulls 251 g on a Gemfan 1636 quad-blade at full throttle on T-Motor's 4S bench.

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1104 motor drawn from T-Motor’s published sizes, not its exact design. Thrust, current and power are T-Motor’s bench figures for the GF1636-4 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 GF1636-4: 119 g of thrust, 4.4 A, 74 W, 1.62 g per watt.
On your quad
1.5 : 1
Thrust to weight at full throttle: four motors pull 1,006 g with the GF1636-4 at 16.8 V.
At 60% throttle they pull 476 g, 0.7 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.

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; four spokes in the top, each forking at the rim, with four M2 holes on a 5 mm circle round the shaft. (T-Motor drawing, specs and test report, T-Motor product page)
- Shaft. 1.5 mm, standing 2.85 mm above the bell. (T-Motor drawing, specs and test report)
- Bearings and magnets. NMB 502ZZ bearings; N52 arc magnets forming 12 poles round a 9-slot stator. (T-Motor product page, T-Motor drawing, specs and test report)
- Base. Blue, with four M2 holes on a 9 mm circle; 24 AWG leads, 75 mm long. (T-Motor product page, 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 7500KV 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 | 111,000 | 11,100 Hz | 66,600 |
| 4S full | 16.8 | 126,000 | 12,600 Hz | 75,600 |
| 6S nominal | 22.2 | 166,500 | 16,650 Hz | 99,900 |
| 6S full | 25.2 | 189,000 | 18,900 Hz | 113,400 |
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 × 4 mm stator, 14.5 mm bell, 11.9 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.
