GEPRC GR2207

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 1.75 kg on 5S

  The 2400KV pulled 1,747 g at full throttle on a GEP 5040 x3 at about 20 V, drawing 44.39 A.

• Three KVs

  GEPRC made the 1900KV for long range on 5 to 6-inch props, the 2400KV for freestyle and the 2700KV for racing.

• NSK bearings, N52H arc magnets

  NSK bearings from Japan, N52H arc magnets and single-strand wire with enamel rated to 180 °C, in a CNC-machined 7075 aluminium body.

• Wire protection

  A guard that GEPRC says keeps the motor wires from touching the rotor.

What to pair it with

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

ESC

GEPRC lists max currents (30 s) of 40 A (1900KV), 45 A (2400KV) and 48 A (2700KV); its tables peak at 50.91 A, for the 2700KV on a DAL5050 x3 at about 16 V. (GEPRC 2400KV page, GEPRC 2700KV page, GEPRC drawing, specs and data)

Props

GEPRC tested DAL5050 x3, GF 5152 x3 and GEP 5040 x3 props and pairs it with its own GEP-P5040 x3; it lists 5 to 6-inch props for the 1900KV and 5-inch for the others. (GEPRC drawing, specs and data, GEPRC KV guide, GEPRC features image)

Battery

4S–5S for the 2400KV and 2700KV, 4S–6S for the 1900KV. (GEPRC drawing, specs and data, GEPRC KV guide)

Frame

Four M3 holes on a 16 × 16 mm pattern, with M3×6, M3×7 and M3×8 button-head screws in the box. (GEPRC 2400KV page, GEPRC drawing, specs and data)

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:

• Bell. CNC-machined 7075 aluminium, with the four-arm top GEPRC first used on its GR2306. (GEPRC 2400KV page, GEPRC features image)
• Stator. 12N14P, wound with single-strand enamelled wire rated to 180 °C, inside N52H arc magnets. (GEPRC drawing, specs and data, GEPRC features image)
• Shaft. A hollow shaft with an M5 thread, held by an aluminium M5 lock nut. (GEPRC 2400KV page, GEPRC drawing, specs and data)
• Bearings. NSK bearings from Japan. (GEPRC 2400KV page, GEPRC features image)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 2400KV 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 22 × 7 mm stator, 26.7 mm bell, 18 mm height, 5 mm shaft, 16 mm mounting circle 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.
