DFRobot Gravity DC Micro Metal Gear Motor with Driver 75:1 Reduction

The DFRobot Gravity DC Micro Metal Gear Motor with Driver is a DC geared motor with a 75:1 reduction ratio and an integrated driver, operating from 3.5-8V DC.

Overview

The motor combines DC motor operation with positional control of a 360-degree servo. Its integrated driver and 3-pin Gravity interface simplify connections, and direction and speed are controlled with a single PWM signal, without requiring a separate motor driver. The driver chip manages all control logic, enabling forward and reverse motion with precise speed adjustment through Pulse Width Modulation (PWM).

Key Features

• 75:1 reduction ratio providing substantial torque for its small size
• Operating voltage of 3.5-8V DC
• Integrated driver with 3-pin Gravity interface
• Forward, reverse and speed control using a single PWM signal
• Control signal: PPM with 1µs resolution and 500Hz PWM frequency
• Static current below 1mA with no PWM control signal

Dimensions and Weight

The unit measures 43 mm x 33 mm x 15 mm and weighs 19 g, making it suited to space-constrained designs.

Applications

The motor is intended for projects requiring controlled, powerful movement from a compact power source, including robotics, automated mechanisms, embedded systems and hobbyist electronics.

Please Note

The embedded control chip consumes a small amount of the input voltage, which results in a slight reduction of the actual voltage and speed delivered to the motor. Choose this DFRobot Gravity DC Micro Metal Gear Motor with Driver for compact motion control projects that require a simple single-signal interface.
