DFRobot Gravity DC Micro Metal Gear Motor with Driver 50:1

The DFRobot Gravity DC Micro Metal Gear Motor with Driver is a compact DC gear motor with a 50:1 reduction ratio, offering a balance of speed and torque for electronics projects.

Overview

The motor is designed for easy integration and is operated through the Gravity interface, which simplifies connections to Arduino and other development boards. It operates within a 3.5V to 8V voltage range and draws approximately 40mA under no load at 6V. It is suited to embedded systems, IoT devices, electronics education, and a wide range of hobbyist and professional applications.

Control and Interface

The motor is driven using a PPM signal with a resolution of 1µs and a pulse width range of 500µs to 2500µs. Clockwise rotation uses pulse widths from 500µs to 1400µs, with 500µs giving maximum speed. A pulse width between 1400µs and 1600µs stops the motor. Anticlockwise rotation uses pulse widths from 1600µs to 2500µs, with 2500µs giving maximum speed. The PWM frequency is set at 500Hz.

Package Contents

• DC micro metal gear motor with driver
• One Gravity 3-pin cable

Dimensions and Weight

The motor measures 3.3 (width) x 1.5 (depth) x 4.3 (height) and weighs 19 g.

Important Note

The embedded control chip consumes a small amount of input voltage, which may slightly reduce the motor voltage and speed.
