7-inch long-range FPV motor

T-Motor Velox V2812

The classic model of T-Motor's Velox cinematic trio, for 7-inch long range and 7–8-inch X8 cinelifters on 6S, in 925KV and 1155KV; the 1155KV pulls 3353 g on a Gemfan 8040 at full throttle on T-Motor's 25.2 V bench.

Drawing the 3D model…

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2812 motor drawn from T-Motor’s published sizes, not its exact design. Thrust, current and power are T-Motor’s bench figures for the GF8040-3 prop at 25.2 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.

On your quad

20.6 : 1

Thrust to weight at full throttle: four motors pull 13,411 g with the GF8040-3 at 25.2 V.

At 60% throttle they pull 5,610 g, 8.6 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.

What you get for $33.90

  • The classic model

    T-Motor calls the V2812 the classic model of its V2808, V2812 and V3008 cinematic range, for 7–8-inch long-range explorers and 7–8-inch X8 cinematic drones.

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 10 s is 63.1 A for the 1155KV and 41.4 A for the 925KV. Ligpower pairs it with T-Motor's F55A II 6S 4-in-1 or C55A 8-in-1. (T-Motor drawing, specs and test report, Ligpower product page)
Props
Ligpower names T-Motor's C7.5 × 4.6. On the bench at full throttle the 1155KV pulled 3234 g on the T7546-3, 3353 g on a Gemfan 8040 and 3014 g on an HQProp 8045. (Ligpower product page, T-Motor drawing, specs and test report)
Battery
6S; T-Hobby suggests a 6S 5200 mAh 75C pack. (T-Motor drawing, specs and test report, T-Hobby product page)
Frame
7–8-inch long-range frames and X8 cinelifters, per T-Motor. Four M3 holes, opposite holes 19 mm apart. (Ligpower product page, T-Motor drawing, specs and test report)

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:

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1155KV 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.

BatteryVoltsNo-load rpm (KV × V)Electrical frequencyESC steps per second
4S nominal14.817,0941,994 Hz11,966
4S full16.819,4042,264 Hz13,583
6S nominal22.225,6412,991 Hz17,949
6S full25.229,1063,396 Hz20,374

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 28 × 12 mm stator, 33.4 mm bell, 26.5 mm height, 19 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.
