1S whoop motor
NewBeeDrone FLOW 0802 Dual Ball Bearing
A 2.15 g whoop motor with two NSK ball bearings in four KVs; on NewBeeDrone's 4 V bench the 27000KV pulls 27.8 g at 6.2 A and the 19000KV 21.34 g at 2.5 A.
- 1S whoops on 31 mm props
- 1S (19000KV, 27000KV)
- JST 1.0 or JST 1.25 motor plugs
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 0802 motor drawn from NewBeeDrone’s published sizes, not its exact design. No-load speed is KV × 3.7 V, a nominal pack for this version. NewBeeDrone’s bench tables for it step by thrust rather than throttle, so they are in the bench data below, not on this readout.
- Max thrust
- 28 g
- AZI 1.0 30MM-3P prop, 4 V
- Weight
- 2.15 g
- with lead and plug; 1.95 g without
- Peak current

Bench data
Redrawn from NewBeeDrone’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. 7075 aluminium in a dark bronze finish, with six spokes on the top. (NewBeeDrone 27000KV page, NewBeeDrone product photos)
- Bearings. Two NSK ball bearings. (NewBeeDrone 27000KV page)
- Stator. 8.4 mm across and 2 mm tall with 9 slots; 12 magnet poles. (NewBeeDrone 27000KV spec sheet, NewBeeDrone 19000KV spec sheet)
- Leads. Three 30 AWG wires with a JST 1.0 3-pin plug: 50 mm on the 27000KV, 30 mm including the plug on the 19000KV. (NewBeeDrone 27000KV spec sheet, NewBeeDrone 19000KV spec sheet)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 27000KV 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 | 399,600 | 39,960 Hz | 239,760 |
| 4S full | 16.8 | 453,600 | 45,360 Hz | 272,160 |
| 6S nominal | 22.2 | 599,400 | 59,940 Hz | 359,640 |
| 6S full | 25.2 | 680,400 | 68,040 Hz | 408,240 |
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 NewBeeDrone’s published sizes: the 8.4 × 2 mm stator, 11.6 mm bell, 8 mm height, 1 mm shaft, 6.6 mm mounting circle and 9 teeth and 12 magnets. Anything NewBeeDrone 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.
