T-Motor F1507

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

• Made for cinewhoops

  T-Motor's second-generation cinewhoop motor, made for 3-inch props; it says the torque gives a smoothness and control comparable to bigger 20-class motors.

• Up to 838.7 g per motor

  At full throttle the 2700KV pulled 838.7 g on a T3140 at about 23.3 V and the 3800KV 673.8 g at about 15.1 V. T-Motor puts the best thrust-to-weight ratio at 52.8.

• M5 prop shaft

  The prop mounts on an M5 × 0.8 threaded shaft standing 11.8 mm above the bell, held with an M5 lock nut; the shaft is 2 mm where it ends under the base.

What to pair it with

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

ESC

T-Motor rates peak current at 22 A (2700KV) and 23 A (3800KV) over 60 s, but its own full-throttle runs on the T3140 drew 23.34 A and 25.87 A; T-Motor benched it with its F35A ESC. (T-Motor specs and test report, T-Motor product page)

Props

3-inch props, per T-Motor. Of the three tri-blades it benched, the T3140 pulled the most at full throttle and the Gemfan GF3035 was the most efficient. (T-Motor product page, T-Motor specs and test report)

Battery

3S–6S for the 2700KV, which T-Motor benched on 6S; 3S–4S for the 3800KV, benched on 4S. (T-Motor specs and test report)

Frame

3-inch cinewhoop frames. Four M2 holes on a 12 mm circle. (T-Motor product page, T-Motor drawing)

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. 18.9 mm across, dark grey, with three swept spokes on the top, their edges machined bright. (T-Motor drawing, T-Motor product page)
• Shaft. M5 × 0.8 threaded above the bell for the prop nut, 2 mm where it ends 1.4 mm below the base, held with an E-clip. (T-Motor drawing, T-Motor specs and test report)
• Base. Four M2 holes on a 12 mm circle; 24 AWG leads, 100 mm long. (T-Motor drawing, T-Motor specs and test report)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 2700KV 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 14-pole rotor has 7 pole pairs, so every turn of the shaft is 7 electrical cycles, and a six-step ESC switches the phases 42 times per turn.

About the 3D model

A generic outrunner drawn from T-Motor’s published sizes: the 15 × 7 mm stator, 18.9 mm bell, 16.5 mm height, 5 mm shaft, 12 mm mounting circle and 12 teeth and 14 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.
