T-Motor F1103

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.

What you get for $11.90

• For toothpicks

  T-Motor built it for 2–3S toothpicks, and T-Hobby offers it as a replacement for tinywhoop motors.

• NMB bearings

  NMB 502Z bearings, which T-Motor picked for steady running at high RPM.

• Stepped shaft

  T-Motor says the stepped 1.5 mm shaft keeps it from pulling out.

• Full bench data

  Thrust, current, RPM, power and motor temperature in 5% steps from 50% throttle on 65 mm props: 235 g at full throttle for the 8000KV on 3S.

What to pair it with

Our reading of T-Motor’s numbers, so your build matches what the motor was tested with.

ESC

Peak current over 60 s is 11.5 A for the 8000KV and 13.6 A for the 11000KV. T-Hobby suggests a 2–3S ESC. (T-Motor drawing and specs, T-Motor test report, T-Hobby product page)

Props

T-Motor benched it on HQProp 65 mm props; T-Hobby lists 65 mm props. (T-Motor test report, T-Hobby product page)

Battery

2S–3S. T-Hobby suggests a 2S 550 mAh or 3S 450 mAh 75C pack. (T-Motor drawing and specs, T-Hobby product page)

Frame

2–3-inch toothpicks or 1.6–2.5-inch whoops of about 80–90 g at take-off, per T-Hobby. Four M2 holes on a 9 mm circle. (T-Hobby product page, T-Motor drawing and specs)

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. 14.4 mm across, gunmetal, with windows in the top and four M2 holes on a 5 mm circle round the shaft. (T-Motor drawing and specs)
• Shaft. 1.5 mm, standing 4 mm above the bell, stepped inside so it cannot pull out. (T-Motor product page)
• Bearings. NMB 502Z ball bearings. (T-Motor product page)
• Base. Four M2 holes on a 9 mm circle; three 24 AWG leads, 75 mm long. (T-Motor drawing and specs)

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.

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, 14.4 mm bell, 10 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.
