Bambu Lab N20 Reduction Gear Motor

The N20 Reduction Gear Motor is a low-power gear motor with a D-shaped output shaft, suitable for applications requiring continuous rotation of objects. It is available in three speed variations: low speed (150 RPM), medium speed (400 RPM), and high speed (1000 RPM).
The motor can be connected to the 4-channel Power Distribution Board (PDB) using a wire pair with SH1.0-2PIN (5cm / 10cm / 20cm).
Important Considerations
-
Use a power supply within the specified operating voltage range.
-
Avoid immersing the motor in water or exposing it to moisture.
-
Use screws of appropriate length to secure the gearbox to prevent thread damage or contact with internal gears.
-
When securing the motor with glue or adhesive, ensure it does not penetrate the gearbox, shaft, or motor interior.
-
Regularly apply a small amount of lubricant or grease to the gearbox to extend its lifespan and reduce noise.
Installation Guide
Connect the motor to a compatible power source within the 3V–7V operating voltage range, using the provided SH1.0-2P wire pair. Ensure correct polarity when connecting to the 4-channel Power Distribution Board (PDB).
-
Secure the gearbox using screws of appropriate length.
-
Avoid over-tightening to prevent damage to the gearbox housing.
-
Do not allow adhesives to penetrate the gearbox or motor housing.
