What you get for $15.90

• Made for 2.5-inch whoops

  Axisflying designed the C145 for 2.5-inch cinewhoops and tiny trainers that need more power and torque, and pairs it with Gemfan D63-3 and D63-5 props.

• N52H arc magnets

  Curved N52H arc magnets, and a magnetic circuit that Axisflying says responds faster.

Props

Gemfan D63-3 and D63-5, which Axisflying recommends and tested; the five-blade D63-5 pulls more. (Axisflying product page, Axisflying spec image (archived))

Bench data

Redrawn from Axisflying’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. Black, with a black top cut into eight spokes and a red ring round the bell's top edge. (Axisflying product photo, Axisflying top-view photo)
• Shaft. 1.5 mm, standing 3 mm above the bell; props fix to four M2 holes on a 5 mm circle in the top. (Axisflying spec image (archived))
• Stator. 14 × 4.5 mm, 9 slots, with 12 curved N52H arc magnets in the bell. (Axisflying product page, Axisflying spec image (archived))
• Leads. 22 AWG silicone wire, 150 mm. (Axisflying spec image (archived))

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 4500KV 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 Axisflying’s published sizes: the 14 × 4.5 mm stator, 18.1 mm bell, 12.7 mm height, 1.5 mm shaft, 9 mm mounting circle and 9 teeth and 12 magnets. Anything Axisflying 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.
