Product Title

GM37-520 37mm DC Gear Motor 12V 24V High Torque Metal Gearmotor

Description

The GM37-520 37mm DC Gear Motor combines a compact 520 brushed DC motor with an all-metal reduction gearbox to provide high torque and reliable low-speed operation for robotics, automation, smart devices, camera mechanisms, and DIY motion-control projects.

The motor features a 37mm gearbox, 6mm D-shaped output shaft, and multiple gear ratios ranging from 6.3:1 to 810:1. Different ratios allow the motor to be configured for higher speed or higher torque depending on the application.

Available in 12V and 24V versions, the GM37-520 is suitable for robotic platforms, smart equipment, motorized mechanisms, camera pan/tilt systems, and other compact drive applications requiring a durable geared DC motor.

A compatible mounting bracket can be used for easier installation.

FAQ

Is this a brushless motor?
No. The GM37-520 shown here is a brushed DC gear motor.

Does the motor include an encoder?
No. This version does not include an encoder.

Can the rotation direction be reversed?
Yes. The rotation direction can be reversed by reversing the DC motor power polarity.

Can the motor speed be controlled?
Yes. A compatible DC PWM motor speed controller can be used to adjust motor speed.

Which voltage should I choose?
Choose the 12V or 24V version according to your power supply and control system. Do not apply 24V to a motor configured for 12V unless the specific motor is rated accordingly.

Which gear ratio provides the highest speed?
The 6.3:1 version provides the highest output speed.

Which ratios are better for high-torque applications?
Higher ratios such as 150:1, 270:1, 450:1, 650:1 and 810:1 provide lower speed and higher output torque. Continuous operating load should remain within the gearbox's allowable limits.
