2–3-inch toothpick FPV motor
EMAX ECO 1106
A 1106 micro motor for 2–3-inch toothpicks: 9N12P, 6.7 g without leads, a 9 × 9 mm M2 mount and a 1.5 mm shaft, in 4500KV for 3S and 6000KV for 2S.
- 2–3-inch toothpicks
- 2S–3S (4500KV) or 2S (6000KV)
- 2 to 3-inch props
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1106 motor drawn from EMAX’s published sizes, not its exact design. No-load speed is KV × 11.1 V, a nominal pack for this version. EMAX publishes no bench data for it.

What to pair it with
Our reading of EMAX’s numbers, so your build matches what the motor was tested with.
- ESC
- EMAX gives a peak current of 11.6 A for the 4500KV on 3S and 12 A for the 6000KV. An ESC rated for 12 A or more covers both. (EMAX spec sheet)
- Props
- EMAX lists 2 to 3-inch props for both. EMAX USA pitches the 4500KV at the larger props in that range on 3S and the 6000KV at the smaller ones on 2S. (EMAX spec sheet, EMAX USA 4500KV page, EMAX USA 6000KV page)
- Battery
- 2S–3S for the 4500KV, 2S for the 6000KV. (EMAX spec sheet)
- Frame
- Four M2 holes on a 9 mm circle (9 × 9 mm), which EMAX says fits the most common micro quad frames. (EMAX spec sheet, EMAX USA 4500KV page)

Inside the motor
A brushless outrunner: the coils stand still in the middle and the magnets spin around them. From the top down:
- Shaft. Steel; 1.5 mm prop-adapter shaft protruding 4.1 mm; 2 mm through the bearings. (EMAX product page, EMAX spec sheet)
- Bell. Anodised; four M2 holes in the top for the prop. (EMAX product page, EMAX spec sheet)
- Stator. The coils are wound on a stack of thin steel laminations: 11 × 6 mm (1106). (EMAX product page)
- Winding. Multi-strand copper. (EMAX product page)
- Bearings. Precision ball bearings. (EMAX product page)
- Base. 4 × M2 holes on a 9 mm circle (9 × 9 mm). (EMAX spec sheet, EMAX product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 4500KV 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 | 66,600 | 6,660 Hz | 39,960 |
| 4S full | 16.8 | 75,600 | 7,560 Hz | 45,360 |
| 6S nominal | 22.2 | 99,900 | 9,990 Hz | 59,940 |
| 6S full | 25.2 | 113,400 | 11,340 Hz | 68,040 |
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 EMAX’s published sizes: the 11 × 6 mm stator, 14.2 mm bell, 14.5 mm height, 1.5 mm shaft, 9 mm mounting circle and 9 teeth and 12 magnets. Anything EMAX 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.
