Bench data

Redrawn from NewBeeDrone’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. NewBeeDrone lists 7075 aluminium alloy. The finish is a dark bronze, and the top has six spokes. (NewBeeDrone product photos)
• Magnets. N52H magnets. (NewBeeDrone product page)
• Stator. 20 mm across and 4 mm tall, stacked from 0.15 mm silicon steel sheets. (NewBeeDrone product page)
• Bearings. NSK or NMB 730ZZ ball bearings. (NewBeeDrone product page)
• Leads. 24 AWG silicone wires. (NewBeeDrone product page)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 2000KV 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 NewBeeDrone’s published sizes: the 20 × 4 mm stator and 12 mm mounting circle. Anything NewBeeDrone 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.
