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, φ18.2 mm, with twelve bars on top joined in six V-shaped pairs. (BrotherHobby product page, BrotherHobby drawing)
• Shaft. 5 mm with an M5 thread, standing 12 mm above the bell. (BrotherHobby drawing)
• Magnets. N52H arc magnets, 12 poles. (BrotherHobby product page)
• Stator. 14 × 7 mm with 9 slots, in 0.15 mm Nippon Steel silicon steel. (BrotherHobby product page)
• Bearings. NSK, 5 × 2 × 2.5 mm. (BrotherHobby product page)
• Base. An open cross, 2 mm thick, with four M2 holes on a 12 mm circle and 26 AWG leads 160 mm long. (BrotherHobby base image, BrotherHobby drawing)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 3600KV 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 BrotherHobby’s published sizes: the 14 × 7 mm stator, 18.2 mm bell, 16.1 mm height, 5 mm shaft, 12 mm mounting circle and 9 teeth and 12 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.
