- 1S micro FPV quads
- 1S
- JST 1.0 motor plugs
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 0703 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 publishes no bench data for it.

Inside the motor
A brushless outrunner: the coils stand still in the middle and the magnets spin around them. From the top down:
- Bell. Silver, with six round holes in the top. (NewBeeDrone product photos)
- Base. A three-arm silver base with three screw holes. (NewBeeDrone product photos)
- Leads. 24 mm leads with a JST 1.0 plug, and solder pads on the motor. (NewBeeDrone product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 16420KV 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 | 243,016 | 24,302 Hz | 145,810 |
| 4S full | 16.8 | 275,856 | 27,586 Hz | 165,514 |
| 6S nominal | 22.2 | 364,524 | 36,452 Hz | 218,714 |
| 6S full | 25.2 | 413,784 | 41,378 Hz | 248,270 |
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 7 × 3 mm stator and 1 mm shaft. 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.
