20mm DC Geared Motor

Specification

Description

I.CH Motion’s 20mm 12V DC Metal Gear Motor, this brushed DC motor and spur gearbox assembly is engineered to boost torque output while reducing operational speed, ideal for industrial applications requiring precise power control.

 

Character

Our 20mm 12V DC metal gear motor integrates a compact 20mm spur gearbox with a customizable gear ratio range of 1:10 to 1:298. This all-in-one solution excels in space-constrained setups that demand low-speed rotation and high torque performance—perfect for automation equipment, robotics, and precision machinery.


For custom parameter adjustments (including voltage, gear ratio, and torque specifications), contact our technical team to tailor the motor-gearbox assembly to your exact application needs.
