## Description

Robust solution for automation, robots and actuators where you need high torque and stable speed. It operates at 12V and delivers 100 RPM output thanks to the precision metal reducer, has a compact 37 mm housing and 6 mm shaft with flat area for secure coupling, low consumption for easy integration into electronic projects.
The DC geared motor, GA37RG, 12VDC, 100RPM is a reliable and robust solution for applications requiring high torque and good speed control.
This model combines a 12V DC motor with a precision metal reducer, providing a reduced speed of 100 revolutions per minute at the output shaft, ideal for automation, robots, actuators or DIY projects.
The solid construction, standard diameter of 37 mm and low current consumption allow easy integration into electronic and mechanical systems. The motor offers a very good balance between power, efficiency and durability, being suitable for continuous operation in constant load applications.

Use:
The motor is powered at 12V DC respecting the polarity for the correct direction of rotation (Plus marked with the + sign next to the terminal). It can be mounted on a mechanical support using the M3 front holes of the reducer and connected directly to wheels, axles or mechanisms through the coupling.
It is recommended to use a motor driver or PWM controller for speed regulation and circuit protection.
For extended lifespan, it is recommended to avoid overloading and ensure proper ventilation.
