The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2306.5 motor drawn from NewBeeDrone’s published sizes, not its exact design. No-load speed is KV × 22.2 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. NewBeeDrone lists 7075 aluminium alloy. The finish is gunmetal grey, and the top has ten spokes. (NewBeeDrone 1850KV page, NewBeeDrone product photos)
- Magnets. N55H magnets. (NewBeeDrone 1850KV page)
- Stator. 23 mm across and 6.5 mm tall, stacked from 0.15 mm silicon steel sheets. (NewBeeDrone 1850KV page)
- Bearings. NSK or NMB 684ZZ ball bearings. (NewBeeDrone 1850KV page)
- Shaft. TC4 titanium alloy. (NewBeeDrone 1850KV page)
- Leads. 20 AWG silicone wires. (NewBeeDrone 1850KV page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1850KV 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 | 27,380 | 3,194 Hz | 19,166 |
| 4S full | 16.8 | 31,080 | 3,626 Hz | 21,756 |
| 6S nominal | 22.2 | 41,070 | 4,792 Hz | 28,749 |
| 6S full | 25.2 | 46,620 | 5,439 Hz | 32,634 |
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 23 × 6.5 mm stator. 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.
