The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1404 motor drawn from NewBeeDrone’s published sizes, not its exact design. No-load speed is KV × 14.8 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. Gunmetal grey, with six spokes on the top and two holes beside the shaft for T-mount props. (NewBeeDrone product photo, NewBeeDrone top-view photo)
- Magnets. N48SH magnets. (NewBeeDrone product page)
- Stator. 14 mm across and 4 mm tall, stacked from 0.2 mm silicon steel sheets. (NewBeeDrone product page)
- Bearings. NSK MR52 ball bearings. (NewBeeDrone product page)
- Leads. 20 AWG silicone wires, 3 cm long. (NewBeeDrone product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 4000KV 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 | 59,200 | 6,907 Hz | 41,440 |
| 4S full | 16.8 | 67,200 | 7,840 Hz | 47,040 |
| 6S nominal | 22.2 | 88,800 | 10,360 Hz | 62,160 |
| 6S full | 25.2 | 100,800 | 11,760 Hz | 70,560 |
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 NewBeeDrone’s published sizes: the 14 × 4 mm stator and 12 mm mounting circle. 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.
