GPG 60 mm gear motors: match the winding, capacitor and gearhead before choosing a ratio

The 2IK / 2RK family combines a compact motor with a separate gearhead. The available electrical table specifically covers reversible 2RK 6 W and 10 W motors, with different 110 V and 220 V windings. For a small feed mechanism or positioning drive, the useful selection question is whether the assembled unit can deliver the required loaded speed and torque within the available mounting space—not simply whether it has a 60 mm face.

Four winding choices at 50 Hz

These are motor-shaft ratings from the 2RK table, before gearbox reduction. The round-shaft model is shown first; its GN counterpart is the pinion-shaft version intended for the listed gearhead. The electrical values below do not establish equivalent 2IK ratings.

Round / pinion modelSupply / powerCurrentMotor rated speedCapacitor
2RK6A-A / 2RK6GN-A 110 V / 6 W 0.24 A 1,200 rpm 3 μF / 250 V
2RK6A-C / 2RK6GN-C 220 V / 6 W 0.12 A 1,200 rpm 0.8 μF / 500 V
2RK10A-A / 2RK10GN-A 110 V / 10 W 0.30 A 1,200 rpm 4 μF / 250 V
2RK10A-C / 2RK10GN-C 220 V / 10 W 0.15 A 1,200 rpm 1 μF / 500 V

A 60 Hz order changes more than the output rpm

Use the frequency-specific capacitor

At 60 Hz the table lists 1,450 rpm and different capacitors: 2.5 μF for the 110 V 6 W winding, 0.7 μF for 220 V 6 W, 3 μF for 110 V 10 W, and 0.8 μF for 220 V 10 W. Keep the listed 250 V or 500 V capacitor voltage class with the corresponding winding. Do not buy a replacement capacitor from motor power alone.

Starting torque is a separate check

The 6 W starting-torque entry falls from 600 g·cm at 50 Hz to 500 g·cm at 60 Hz; the 10 W entry changes from 950 to 800 g·cm. These are motor values, not allowable gearhead output torque. A loaded start, repeated reversal or high-inertia load needs the assembled drive checked for its actual cycle.

Read the gearbox table without promising synchronous output speed

The catalogue bases these speed headings on synchronous motor speed. It explicitly says rated-load output is about 10–20% lower. For example, the 50 rpm heading implies roughly 40–45 rpm under that stated condition, not a guaranteed regulated 50 rpm. Torque values are allowable-load entries; the N·m values here use the catalogue conversion kg·cm × 9.8 ÷ 100.

Speed headingRatio at 50 / 60 Hz6 W allowance10 W allowance
100 rpm 15 / 18 5 kg·cm ≈ 0.49 N·m 8.3 kg·cm ≈ 0.81 N·m
50 rpm 30 / 36 9.7 kg·cm ≈ 0.95 N·m 16 kg·cm ≈ 1.57 N·m
30 rpm 50 / 60 16 kg·cm ≈ 1.57 N·m 25 kg·cm ≈ 2.45 N·m
15 rpm 100 / 120 25 kg·cm ≈ 2.45 N·m 25 kg·cm ≈ 2.45 N·m

Resolve these three assembly details before releasing a replacement order

Motor shaft and gearhead shaft are different interfaces

The catalogue round motor shaft is 6 mm, while the illustrated gearhead output is 8 mm. The motor and gearbox drawings also show different locating diameters. A request for “60 mm motor” does not specify the driven coupling. Send the output-shaft and mounting measurements from the installed assembly.

Use one matched drawing revision

The linked 2025 PDF assembly drawing for 2RK6–10GNC with 2GN gearhead shows a 61 mm square envelope, 75 mm motor body and 8 mm output shaft with a 32 mm extension. The catalogue illustration uses a 60 mm face. The PDF also assigns 32 mm gearhead length to ratios 5–20 and 41.5 mm to higher listed ratios, differing from the catalogue’s length grouping. Require a drawing approved for the exact ordered ratio; do not combine dimensions from these two revisions.

Allow space for the chosen connection housing

The separate T-version drawing adds a side terminal enclosure; it is not the same envelope as the lead-wire version. State lead-wire or terminal-box construction, cable exit direction, required reversal cycle and loaded rpm in the inquiry. The page gives class B insulation, −10 to +40°C ambient and non-condensing operation; these do not by themselves establish suitability for a wet or enclosed machine.

CATALOGUE OVERVIEW

About this motor series

GPG lists the 2IK / 2RK as a 60 mm AC geared-motor family. Its published operating conditions include ambient temperatures from -10°C to +40°C and non-condensing humidity below 95%. The catalogue specifies class B insulation and a winding temperature rise no greater than 75 K at rated operation. Output speed and torque depend on the selected motor and gearbox combination; request the dimensional drawing and matched ratio before specifying the assembly.
