The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2307 motor drawn from T-Motor’s published sizes, not its exact design. No-load speed is KV × 22.2 V, a nominal pack for this version. T-Motor publishes no bench data for it.

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 40.4 A for the 1950KV and 36 A for the 2550KV, by T-Motor's spec tables. Ligpower pairs it with T-Motor's F55A PRO II 6S 4-in-1. (T-Motor spec tables, Ligpower product page)
Props: Ligpower names T-Motor's P49436 or T5143S. (Ligpower product page)
Battery: 6S for the 1950KV, 4S–5S for the 2550KV. (T-Motor spec tables)
Frame: 5-inch quads, per T-Motor. Four M3 holes on a 16 mm circle. (Ligpower product page, T-Motor drawing)

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 (Unibell), 28.6 mm across, rose gold with a faceted outer surface; six spokes in the top, each forking near the rim, round a knurled hub. (T-Motor product page, T-Motor drawing)
Shaft. Titanium, 4 mm by T-Motor's table, with 7 mm of thread; it stands 12 mm above the bell. (T-Motor product page, T-Motor spec tables, T-Motor drawing)
Base. Rose gold, with four M3 holes on a 16 mm circle; 20 AWG leads, 150 mm long. (T-Motor product page, T-Motor drawing, T-Motor spec tables)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1950KV 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	28,860	3,367 Hz	20,202
4S full	16.8	32,760	3,822 Hz	22,932
6S nominal	22.2	43,290	5,051 Hz	30,303
6S full	25.2	49,140	5,733 Hz	34,398

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 23 × 7 mm stator, 28.6 mm bell, 18.95 mm height, 16 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.
