DFRobot 12V Geared DC Motor Brushed 40 RPM 1:150 Ratio

DFRobot 12V Geared DC Motor is a brushed DC motor with a 1:150 metal worm gearbox, delivering a no-load speed of 40 RPM at a rated voltage of 12V.

The motor is designed for reliable, high-torque applications and features a durable metal worm gearbox built for long service life. Its worm drive mechanism provides self-locking, so the output shaft cannot be easily back-driven, which makes it suitable for applications that need a secure hold or positioning. It connects via a simple two-wire system and supports both directional control and PWM speed control.

Key Features

• High torque output with a stall torque of 8 kg/cm
• Self-locking worm gear that prevents unwanted movement when power is off
• Operating voltage range of 6V to 15V
• Speed and direction control via PWM and polarity reversal
• Metal gearbox for enhanced durability compared with plastic alternatives
• Compact form factor for easy integration into assemblies

Dimensions and Weight

The motor measures 3.3 (width) x 1.5 (depth) x 4.3 (height) and weighs 140 g.

Applications

With its compact dimensions, the motor is suited to space-constrained designs, including robotics, automation, model making and educational kits. Its robust construction supports demanding tasks that require significant force at low speeds.

Usage Note

To ensure longevity and prevent damage to the internal gearbox, avoid stalling the motor for extended periods.

Choose the DFRobot 12V Geared DC Motor for projects that require a compact, self-locking geared motor with controllable 40 RPM output.
