APPLICATIONS

For compact mechanisms requiring a geared DC drive with a 6 mm output shaft. Select the motor version and gear ratio according to the required rated speed and torque, then check the mounting pattern and gearbox length against your assembly.

WHAT’S INCLUDED

  • 1 × 37-3530 DC gear motor in the selected configuration

FAQ

What is the difference between the 6000 RPM and 10000 RPM versions?
These values identify the motor speed versions before gear reduction. Output speed depends on the selected gear ratio. For example, the 60:1 gearbox provides 100 RPM at no load with the 6000 RPM version and 166 RPM with the 10000 RPM version.

Which configurations provide 35 kgf·cm of rated output torque?
The 506:1, 540:1, 810:1, and 1069:1 configurations are listed at 35 kgf·cm for both motor speed versions. Their rated output speeds are shown in the performance tables.

Is no-load output RPM the speed during normal loaded operation?
No-load RPM is measured without an applied output load. For example, the 12V or 24V 6000 RPM version with a 60:1 gearbox is listed at 100 RPM without load and 78 RPM at its rated torque of 8 kgf·cm.

Can this motor run forward and reverse at adjustable speeds?
Yes. It supports speed adjustment and bidirectional operation. Use the electrical specifications to select an appropriate external brushed DC motor controller.

What shaft and mounting dimensions should I check?
The motor uses a 6 mm D-shaft with a 5 mm dimension across the flat. The front face has six M3 mounting holes on a 31 mm bolt circle. Check the shaft axis offset and body length against your assembly.
