Bench data

Redrawn from BrotherHobby’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:

• Bell. 7075 aluminium bell cap, φ34 mm, hard anodised, with five spokes. (BrotherHobby product page, BrotherHobby infographic and drawing)
• Shaft. SUS420 heat-treated steel, 5 mm with an M5 thread. (BrotherHobby product page, BrotherHobby infographic and drawing)
• Magnets. N52H arc magnets, 14 poles. (BrotherHobby product page, BrotherHobby infographic and drawing)
• Stator. 28 × 16 mm with 12 slots, in 0.2 mm Kawasaki silicon steel, wound with TU1-grade enamelled wire. (BrotherHobby product page, BrotherHobby infographic and drawing, BrotherHobby 810KV test report)
• Bearings. NMB, 12 × 6 × 4 mm. (BrotherHobby product page)
• Base. 7075 aluminium, with four M3 holes on a 19 mm circle and 18 AWG leads 250 mm long. (BrotherHobby product page, BrotherHobby infographic and drawing)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 810KV 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 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 BrotherHobby’s published sizes: the 28 × 16 mm stator, 34 mm bell, 5 mm shaft, 19 mm mounting circle and 12 teeth and 14 magnets. Anything BrotherHobby 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.
