GPG G2BLD 60 mm: select the motor speed first, then the 2GN ratio

The 60 mm square-box brushless assembly pairs a G2BLD motor with a 2GN gearhead. Its 15 W and 25 W ratings do not describe one universal winding: the 25 W table includes 12, 24 and 48 V entries, and the 12 V entry shows both 1,800 and 3,000 rpm conditions. The gearhead’s published output table is specifically based on a 1,800 rpm motor.

Motor-side ratings to send with the controller request

Keep these motor ratings separate from geared-output ratings. The table gives a common 46.5 mm motor-body length. It does not identify a compatible driver or the Hall-sensor pinout, so voltage and current alone are insufficient to order the control electronics.

Power / supplyRated currentMotor speedMotor torque
15 W / 12 V DC 2.2 A 1,800 rpm 0.08 N·m
25 W / 12 V DC 3.4 A 1,800 rpm 0.13 N·m
25 W / 12 V DC 3.4 A (shared table entry) 3,000 rpm 0.08 N·m
25 W / 24 V DC 1.9 A 1,800 rpm 0.13 N·m
25 W / 48 V DC 1.0 A 1,800 rpm 0.13 N·m

A worked selection: the published 25 W, 24 V, ratio-25 combination

Read the full combination

The catalogue example is G2BLD25-24-18S/2GN25K: 25 W, 24 V, 1,800 rpm motor and ratio 25. For that ratio, the output table lists 72 rpm and an allowable load of 2.42 N·m for 25 W. The 15 W row at the same ratio is 1.45 N·m; the gearbox ratio alone does not establish the delivered torque.

A larger ratio reaches a torque ceiling

At ratio 30 the 25 W row reaches 2.5 N·m, and higher listed ratios stay at 2.5 N·m. The 15 W row first reaches that allowance at ratio 50. Choosing a still higher ratio reduces speed; it does not authorize unlimited torque multiplication. Keep transient loads and starts separate from this listed allowable-load value.

Do not apply the 1,800 rpm table to the 3,000 rpm option

At ratio 25, dividing 3,000 by 25 gives 120 rpm, but that arithmetic is not a published 3,000 rpm output-load rating. The faster motor row has 0.08 N·m rather than 0.13 N·m. Ask for the permitted geared output at that exact operating point before carrying over the 72 rpm row’s 2.42 N·m allowance.

Two gearhead lengths and one mounting check

Ratios 3–20: short gearheadThe dimension table assigns L = 32 mm. Added to the 46.5 mm motor body, the drawing’s body lengths total 78.5 mm before the separately dimensioned output-shaft extension. The frame is 60 mm square with an 8 mm output shaft and a 32 mm extension. Check coupling engagement against the flat shown in the drawing, not only nominal shaft diameter.
Ratios 25–200: longer gearheadHere L = 41.5 mm, giving 88 mm for those body lengths. The ratio-25 worked example therefore uses this longer package. The torque table also shows ratios 250 and 300, but the dimensional grouping stops at 200; obtain the corresponding drawing rather than assuming the same length for those entries.
Controller and cable clearance remain part of the assemblyThe motor drawing shows a connector above the body. Reserve clearance for the connected cable and confirm phase, feedback and power connections with the selected driver. Specify actual loaded speed, starts per hour, reversal behaviour and required supply tolerance. Published use conditions are 0 to +40°C, below 85% humidity without condensation, and class E insulation; an enclosure’s internal temperature must be assessed separately.

CATALOGUE OVERVIEW

About this motor series

GPG’s square-housing 60 series combines a brushless DC motor with a reduction gearbox. The source identifies 15 W and 25 W versions and provides separate drawing packages for reduction ratios 3–20 and 25–200. The published environment is 0°C to +40°C with non-condensing humidity below 85%. Confirm the controller, exact reduction ratio, output torque and drawing for the intended assembly.
