GEPRC GR2306

What it pulls

GEPRC’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.

What you get

• About 1.85 kg on 5S

  It pulled 1,848 g at full throttle on an HQ 6045 at 20 V, drawing 37.32 A, and 1,570 g at 16 V.

• Efficient at part throttle

  GEPRC gives more than 83% efficiency between 4 and 8 A, and says thrust and efficiency are best between 60% and 80% throttle.

• 0.15 mm air gap

  N52H arc magnets sit 0.15 mm from the stator, on NSK bearings.

• Balanced to 2 mg

  GEPRC says each motor is dynamically balanced to within 2 mg.

What to pair it with

Our reading of GEPRC’s numbers, so your build matches what the motor was tested with.

ESC

GEPRC gives a max current of 35 A for 15 s; its table peaks at 37.32 A, on an HQ 6045 at 20 V. (GEPRC product page, GEPRC data table)

Props

6 to 7-inch, says GEPRC; it tested an HQ 6045 and a GEP 5040 x3. (GEPRC product page, GEPRC data table)

Battery

3S–6S; GEPRC tested it at 16 V and 20 V. (GEPRC product page, GEPRC data table)

Bench data

Redrawn from GEPRC’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:

• Body. CNC-machined 7075 aluminium, with a top of four split arms that GEPRC says moves more air. (GEPRC product page)
• Magnets. N52H arc magnets with a 0.15 mm gap to the stator. (GEPRC product page)
• Bearings. NSK bearings from Japan. (GEPRC product page)
• Balance. Dynamically balanced to within 2 mg. (GEPRC product page)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1600KV 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 GEPRC’s published sizes: the 23 × 6 mm stator, 28.49 mm bell, 4 mm shaft and 12 teeth and 14 magnets. Anything GEPRC 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.
