DESCRIPTION
The 36-555 combines a brushed DC motor, an inline planetary gearbox, and a rear-mounted magnetic encoder with A/B signal outputs. It is available in 12V and 24V versions with 6 mm or 8 mm output shaft options.
Select the voltage, nominal no-load output speed, and shaft diameter required for your assembly. Use the performance table to compare rated output speed and torque. Gearbox length and motor weight vary with the reduction ratio.
The motor supports adjustable speed and forward and reverse rotation. Encoder feedback provides signals for monitoring motor rotation with a suitable external control system.

WHAT’S INCLUDED
- 1 × 36-555 DC planetary gear motor with encoder in the selected configuration
FAQ
Does this planetary gear motor include an encoder?
Yes. It has a rear-mounted magnetic encoder with A and B signal outputs for monitoring motor rotation.
What does the RPM in the variant selector mean?
The selector shows nominal no-load output speed. For example, the 120 RPM option has a 50:1 gearbox and delivers 100 RPM at its rated output torque of 15 kgf·cm.
Why do the 120 RPM and 180 RPM options both use a 50:1 gearbox?
They use different motor speed versions. The 120 RPM option is rated at 100 RPM under load, while the 180 RPM option is rated at 160 RPM under load. Both are listed at 15 kgf·cm rated output torque.
Can I select a 6 mm or 8 mm output shaft?
Yes. Choose the required diameter under Shaft Diameter. The dimension drawing on this page describes the 8 mm shaft version.
Can the motor run forward and reverse at adjustable speeds?
Yes. Use a brushed DC motor controller suitable for the selected motor voltage and current requirements. Encoder feedback requires an appropriate external control system.
Which low-speed options provide 60 kgf·cm rated torque?
The documented 8.3, 10, 14, and 16 RPM configurations are rated at 60 kgf·cm. Refer to the performance table for their corresponding rated output speeds.
