## Description

Brushed DC motor with integrated metal gear, ideal for actuators and automations that require slow and controlled movement. Operates at 12V and delivers 7 RPM with stable torque, metal gears provide durability and efficient power transmission. Suitable for robots, small conveyors and industrial projects where reliability matters.
Brushed DC motor, JGB37-520, with integrated metal gearbox, designed for applications that require low rotational speed and high torque.
It operates at 12VDC and provides an unloaded speed of approximately 7 RPM, making it suitable for actuating mechanisms, automated systems, robots, small conveyors, or other projects where slow and controlled movement is required. The metal gear reducer ensures consistent operation, increased durability, mechanical stability, and efficient torque transmission, even under load.

Usage:
The motor is powered at 12VDC, observing the correct polarity. It is recommended to use a motor driver or a suitable controller for start, stop, and direction control. The power supply must support the current peaks at startup and under heavy load, so a margin above the rated current is recommended. The motor is intended for applications requiring low speed combined with high torque, reliability, and mechanical strength. Do not exceed the maximum allowable torque and avoid prolonged shaft stall to prevent damage to the gears.
Dimensions:
L corresponds to the length in mm depending on the gear ratio.
