DESCRIPTION
The 16-030 micro DC planetary gear motor combines a 16 mm inline planetary gearbox with a compact brushed DC motor and a 3 mm D-shaped output shaft. Available in 6V and 12V versions, it supports adjustable speed and forward and reverse rotation.
Select the nominal no-load output speed, then check the corresponding rated output speed and torque in the performance table. Gearbox length varies with the reduction ratio.

APPLICATIONS
For compact mechanisms requiring an inline planetary gear drive. Check rated output speed, torque, shaft dimensions, and mounting spacing against your assembly before selecting a configuration.
WHAT’S INCLUDED
- 1 × 16-030 micro DC planetary gear motor in the selected voltage and speed configuration
FAQ
Is the selected RPM measured under load?
The selector shows nominal no-load output speed. For example, the 93 RPM option is rated at 68 RPM and 0.8 kgf·cm under rated load.
Which option delivers 8 kgf·cm of rated torque?
The 10 RPM option uses a 1026:1 gearbox and delivers 8 RPM at its rated output torque of 8 kgf·cm.
Can this micro gear motor run forward and reverse?
Yes. It supports forward and reverse rotation and adjustable speed. Refer to the electrical specifications when selecting an external brushed DC motor controller.
What coupling fits the shaft?
Select a coupling designed for a 3 mm D-shaft. Check the 2.5 mm dimension across the flat, shaft projection, and flat length against your coupling.
Does the gearbox length change with output speed?
Yes. Gearbox length ranges from 12.5 to 23 mm across the four gearbox stages. The dimensions table lists the gear ratios assigned to each stage.
