GGM K12-1230 Series Planetary Geared Motor

GGM K12-1230 Series Planetary Geared Motor

The GGM K12-1230 Series is a DC Planetary Geared Motor with a 12mm body diameter. The product integrates the KD1230 DC motor with a coaxial planetary gearbox, creating a compact drive assembly for space-constrained applications.

The K12-1230 series offers three motor options: KD1230LB DC 2.4V, KD1230LC DC 3V, and KD1230H1 DC 13V. Each motor can be paired with 6 gear ratios ranging from 1/4 to 1/4096, meeting various speed and output torque requirements.

Compared to standard DC motors without gearboxes, the GGM K12-1230 allows for reduced output speed and increased torque within a 12mm diameter package. It is an ideal choice for mini robots, testing equipment, small actuators, and OEM products powered by DC sources.

Key Features of the GGM K12-1230 Series

Compact Ø12mm Design

The GGM K12-1230 features a 12mm body diameter, a Ø2mm output shaft, and a 9.5mm shaft extension. The front of the gearhead includes two M2 threaded holes with a 2.5mm thread depth, facilitating direct mounting to brackets or equipment chassis.

The gearbox length varies according to the gear ratio. Therefore, when designing the mounting space, it is essential to verify the body diameter, gearhead length, motor length, and output shaft dimensions.

Three DC Motor Options

The K12-1230 Series utilizes three motor models:

• KD1230LB: DC 2.4V voltage.

• KD1230LC: DC 3V voltage.

• KD1230H1: DC 13V voltage.

These models have different current, speed, and torque characteristics. Selection should be based on the device's actual power supply, required output speed, and load requirements.

Six Gear Ratios

The GGM K12-1230 provides the following gear ratios:

• 1/4

• 1/16

• 1/64

• 1/256

• 1/1024

• 1/4096

Low gear ratios are suitable for mechanisms requiring higher output speeds. High gear ratios help reduce output speed to lower levels while increasing the length of the planetary gearhead.

Applications of the GGM K12-1230 Series

The GGM K12-1230 Series is suitable for small DC drive assemblies requiring compact installation dimensions and various output speed options, including:

• Mini robots and electromechanical models.

• Small-sized actuators.

• Testing and measurement equipment.

• Rotating mechanisms in desktop devices.

• Mini feeding and dosing units.

• Devices using low DC power sources.

• OEM drive assemblies with limited space.

Actual application suitability should be verified based on supply voltage, speed, load torque, operating time, and mounting method.

How to Select the GGM K12-1230 Series

First, determine the device's supply voltage to select the correct motor:

• KD1230LB for DC 2.4V supply.

• KD1230LC for DC 3V supply.

• KD1230H1 for DC 13V supply.

Next, determine the required output speed and compare it with the gear ratio table. Ratios of 1/4 or 1/16 are suitable when the mechanism requires higher speeds. Ratios of 1/64 and 1/256 are suitable for medium or low speed requirements. Ratios of 1/1024 and 1/4096 are used when very slow rotation is needed.

In addition to speed, check the load torque, motor current, operating time, reversing requirements, and power supply current capacity. Do not use the stall torque as the operating torque of the mechanism.

Mechanical dimensions should also be verified before ordering, including:

• Body diameter Ø12mm.

• Output shaft Ø2mm.

• Shaft length 9.5mm.

• Two M2 threaded holes.

• Gearhead length according to gear ratio.

Notes on Replacing the GGM K12-1230

When replacing the GGM K12-1230 geared motor, ensure the correct motor model (KD1230LB, KD1230LC, or KD1230H1), supply voltage, and gear ratio code are used.

Different gear ratios have different gearhead lengths. Therefore, do not only check the 12mm body diameter; verify the length L, shaft dimensions, and mounting hole positions.

Do not use the stall torque in the motor table as the continuous operating torque. The DC power source must have the appropriate voltage and current capacity for the specific motor model.
