5-inch FPV racing motor

T-Motor F50 2207

T-Motor's 5-inch racing motor: 28.56 g without leads, and 2136 g at full throttle on its 24 V bench with a T-Motor F5146 (2150KV).

  • 5-inch racing
  • 6S (24 V)
  • 5-inch tri-blades with small to medium pitch
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 2207 motor drawn from T-Motor’s published sizes, not its exact design. Thrust, current and power are T-Motor’s bench figures for the F5146 prop at 24 V, read straight across between its throttle steps. Its data starts at 10% throttle.

Version

Benched at about 24 V on T-Motor's F5146, HQProp's MCK and Gemfan's 51377-3; 2136 g at full throttle on the F5146.

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.

At 60% with the F5146: 1,120 g of thrust, 17.2 A, 410 W, 2.73 g per watt.

On your quad

13.1 : 1

Thrust to weight at full throttle: four motors pull 8,544 g with the F5146 at 24 V.

At 60% throttle they pull 4,480 g, 6.9 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 to pair it with

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

ESC
Peak current is 54.8 A for the 2150KV and 56.63 A for the 2200KV. T-Motor recommends its F60A Mini 8S 4-in-1 (AM32). (T-Motor drawing, specs and test data, T-Motor product page)
Props
T-Motor recommends 5-inch tri-blades with small to medium pitch, such as its F5146. At full throttle the 2150KV pulled 2136 g on the F5146, 2100 g on Gemfan's 51377-3 and 1983 g on HQProp's MCK. (T-Motor drawing, specs and test data)
Battery
6S, rated 24 V. (T-Motor drawing, specs and test data)
Frame
5-inch X4 racing frames. T-Motor recommends keeping the take-off weight within 500 g, 800 g at most. Four M3 holes on a 16 mm circle. (T-Motor drawing, specs and test data)

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 2150KV 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 nominal14.831,8203,712 Hz22,274
4S full16.836,1204,214 Hz25,284
6S nominal22.247,7305,569 Hz33,411
6S full25.254,1806,321 Hz37,926

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 22 × 7 mm stator, 27 mm bell, 18.75 mm height, 5 mm shaft, 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.
