What to pair it with

Our reading of Diatone’s numbers, so your build matches what the motor was tested with.

ESC

Diatone's maximum currents are 13.48 A (4000KV) and 11.95 A (3000KV), so a 15 A or larger ESC covers both. (Diatone product page (archived), Diatone 4000KV spec sheet)

Props

2.5- to 4-inch toothpick props; Diatone's bench test used a GF D63. (Diatone product page (archived), Diatone 4000KV spec sheet)

Battery

3S–4S for the 4000KV, 3S–6S for the 3000KV. (Diatone product page (archived))

Frame

Four M2 holes on a 12 × 12 mm pattern. (Diatone product page (archived), Diatone 4000KV spec sheet)

Bench data

Redrawn from Diatone’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:

• Shaft. 2 mm; the prop mounts on a 1.5 mm stub standing 1.6 mm above the top, which has four M2 holes on a 5 mm circle. (Diatone product page (archived), Diatone 4000KV spec sheet)
• Stator. The coils are wound on a stack of thin steel laminations: 14 × 4 mm (1404). (Diatone product page (archived))
• Winding. 240 °C high-temperature enamelled wire. (Diatone product page (archived), Diatone 4000KV spec sheet)
• Bearings. 5 × 2 × 2.5 mm. (Diatone product page (archived))
• Base. 4 × M2 on 12 × 12 mm. (Diatone product page (archived), Diatone 4000KV spec sheet)

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.

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 Diatone’s published sizes: the 14 × 4 mm stator, 20.5 mm bell, 13.4 mm height, 1.5 mm shaft, 12 mm mounting circle and 9 teeth and 12 magnets. Anything Diatone 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.
