GA25-370 DC Gear Motor with Encoder 12V 130RPM with Bracket
The GA25-370 DC Gear Motor with Encoder combines a reliable 12V brushed DC motor, a precision metal gearbox, and a built-in quadrature encoder into a compact package. Operating at 130 RPM with an output torque of 4.4 kg.cm, this motor is well suited for projects that require a balance of speed and torque, such as robotic vehicles, conveyor systems, and automated mechanisms.
The integrated encoder provides pulse outputs that enable microcontrollers and motor controllers to accurately monitor shaft speed, direction, and position for closed-loop control. The included metal mounting bracket allows quick and secure installation, making this motor an excellent choice for Arduino, Raspberry Pi, STM32, ESP32, and other embedded control platforms.
Features:
- Integrated quadrature encoder for real-time speed and position feedback.
- Durable metal gearbox for extended operating life.
- Balanced speed and torque performance.
- Compact cylindrical design for easy installation.
- Supports closed-loop motor control.
- Smooth forward and reverse rotation.
- Suitable for PWM speed control.
- Compatible with common DC motor driver modules.
- Includes sturdy metal mounting bracket.
- Low noise and stable operation.
- Ideal for robotics and automation systems.
- Easy integration with embedded development platforms.
