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, φ38.2 mm, hard anodised, with a flat top: six windows round the rim, three curved slots round the shaft and six M3 holes on a 23 mm circle for the prop adapter. (BrotherHobby product page, BrotherHobby exploded view, BrotherHobby drawing)
• Shaft. SUS420 heat-treated steel, 5 mm with an M5 thread, standing 18 mm above the bell. (BrotherHobby exploded view, BrotherHobby drawing)
• Magnets. N52H arc magnets, 14 poles. (BrotherHobby product page, BrotherHobby exploded view)
• Stator. 32.5 × 12 mm with 12 slots, in non-oriented silicon steel, wound with TU1-grade enamelled wire. (BrotherHobby exploded view, BrotherHobby 780KV test report)
• Bearings. NMB, 12 × 6 × 4 mm. (BrotherHobby product page)
• Base. 7075 aluminium, 8.2 mm tall, with four M3 holes on a 19 mm circle and 16 AWG leads 300 mm long. (BrotherHobby product page, BrotherHobby drawing)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 710KV 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 32.5 × 12 mm stator, 38.2 mm bell, 28.7 mm height, 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.
