2S whoop motor
NewBeeDrone 0802 Unibell Espresso Edition
A 2.08 g unibell whoop motor for 2S that pulls 55.4 g at 4.6 A on an Azi three-blade at 8 V in NewBeeDrone's test.
- 2S whoops
- 2S (rated 8.4 V)
- 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 × 7.4 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
- 55 g
- AZI 1.0 3B prop, 8 V
- Weight
- 2.08 g
- each, with wire and plug
- Peak current
- 4.6 A
- full throttle
- Max power
- 37 W
- full throttle

What you get for $34.99
Unibell, no C-clip
NewBeeDrone's second-generation design pairs a unibell with a double step shaft and drops the C-clip on top of the bell, which it says improves balance.

55.4 g on 2S
At 4.6 A and 36.8 W it pulls 55.4 g on an Azi three-blade prop at 8 V.

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. A unibell in a copper colour (the Espresso Edition), with six openings in the top. (NewBeeDrone product page, NewBeeDrone product photos)
- Shaft. 1 mm double step shaft standing 5 mm above the bell, with no C-clip on top. (NewBeeDrone product page, NewBeeDrone spec sheet)
- Stator. 8.4 mm across and 2 mm tall with 9 slots; 12 magnet poles in the bell. (NewBeeDrone spec sheet)
- Leads. Three 30 AWG silicone wires, 50 mm including a JST 1.0 3-pin plug, soldered to pads on the motor. (NewBeeDrone product page, NewBeeDrone spec sheet)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 14000KV 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 | 207,200 | 20,720 Hz | 124,320 |
| 4S full | 16.8 | 235,200 | 23,520 Hz | 141,120 |
| 6S nominal | 22.2 | 310,800 | 31,080 Hz | 186,480 |
| 6S full | 25.2 | 352,800 | 35,280 Hz | 211,680 |
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, 11.5 mm bell, 8.6 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.
