DeepSpace Aether 1203

What it pulls

DeepSpace’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.

What you get for $12.90

• About 210 g on 3S

  On DeepSpace’s 12 V bench it pulled 209.8 g at full throttle on a GF2216S and 207.5 g on an HQ 2.2×1.6×3, drawing 13.2 A at 11.9 V on each.

• 4.9 g

  4.9 g with its 60 mm, 28 AWG cable, which DeepSpace pitches as light and compact for fast, precise response.

• Prop mount on the bell

  A 1.5 mm shaft with four M2 holes on a 5 mm circle in the top of the bell.

What to pair it with

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

ESC

DeepSpace gives a 13.2 A peak, the full-throttle current on both of its 2.2-inch test props at 11.9 V. (DeepSpace spec image)

Props

DeepSpace tested two props on 3S: at full throttle 207.5 g on the HQ 2.2×1.6×3 and 209.8 g on the GF2216S. (DeepSpace spec image)

Battery

Rated for 2S–3S; DeepSpace benched it on 3S (12 V) and names 3S bare-prop and whoop quads of 2 to 2.2 inches. (DeepSpace spec image, DeepSpace product page)

Frame

Four M2 holes on a 9 mm circle. (DeepSpace spec image)

Bench data

Redrawn from DeepSpace’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. 1.5 mm, standing 3.7 mm above the bell; four M2 holes in the bell’s top on a 5 mm circle. (DeepSpace spec image)
• Stator. The coils are wound on a stack of thin steel laminations: 12 × 3 mm (1203). (DeepSpace product page)
• Base. 4 × M2 holes on a 9 mm circle, in a 1.8 mm base plate. (DeepSpace spec image)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 8000KV 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 DeepSpace’s published sizes: the 12 × 3 mm stator, 15.4 mm bell, 10.3 mm height, 1.5 mm shaft, 9 mm mounting circle and 9 teeth and 12 magnets. Anything DeepSpace 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.
