75 mm 1S–2S whoop motor
Hypetrain Dime V2 1002
A 2.5 g 1002 motor for 75 mm whoops: 24000KV for 1S or 15000KV for 2S, on a 1.5 mm shaft and a three-hole 9 × 9 mm mount.
- 1S–2S 75 mm whoops such as Rotor Riot's Vision40
- 1S (24000KV) or 2S (15000KV)
- Props for 1.5 mm shafts
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1002 motor drawn from Hypetrain’s published sizes, not its exact design. No-load speed is KV × 3.7 V, a nominal pack for this version. Hypetrain publishes no bench data for it.

What to pair it with
Our reading of Hypetrain’s numbers, so your build matches what the motor was tested with.
- Props
- Props with a 1.5 mm bore, sized for 75 mm whoops. Hypetrain publishes no bench data. (Hypetrain product page)
- Battery
- 1S for the 24000KV, 2S for the 15000KV. (Hypetrain product page)
- ESC
- Hypetrain lists 14 A max continuous current and 52 W max continuous power, both for 3S; the two don't match each other (52 W on 3S is under 5 A), so they are a poor guide for sizing a whoop board. (Hypetrain product page)
- Frame
- Three holes on a 9 × 9 mm pattern; the plug is a JST-1.25. A screw set comes with each motor. (Hypetrain product page, Hypetrain base photo)

Inside the motor
A brushless outrunner: the coils stand still in the middle and the magnets spin around them. From the top down:
- Shaft. 1.5 mm. (Hypetrain product page)
- Stator. The coils are wound on a stack of thin steel laminations: 10 × 2 mm (1002). (Hypetrain product page)
- Base. 9 × 9 mm pattern, 3 holes (the hole count is from the photo of the base). (Hypetrain product page, Hypetrain base photo)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 24000KV 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 | 355,200 | 35,520 Hz | 213,120 |
| 4S full | 16.8 | 403,200 | 40,320 Hz | 241,920 |
| 6S nominal | 22.2 | 532,800 | 53,280 Hz | 319,680 |
| 6S full | 25.2 | 604,800 | 60,480 Hz | 362,880 |
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 Hypetrain’s published sizes: the 10 × 2 mm stator, 13.5 mm bell, 7.75 mm height, 1.5 mm shaft and 9 mm mounting circle. Anything Hypetrain 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.
