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

The DFRobot Gravity DC Micro Metal Gear Motor with Driver offers a compact and convenient solution for your electronics projects. Designed for easy integration, this motor is operated through the Gravity interface, simplifying connections to Arduino and other development boards.

This motor operates within a 3.5V to 8V voltage range and features a 50:1 reduction ratio, providing an optimal balance of speed and torque. At 6V, it draws approximately 40mA under no load, ensuring efficient performance. Whether you are developing embedded systems, designing IoT devices, or educating on electronics, this unit is suited for 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. For clockwise rotation, the pulse width ranges from 500µs to 1400µs, with 500µs yielding maximum speed. To stop, a pulse width between 1400µs and 1600µs is used. For anticlockwise rotation, the pulse width extends from 1600µs to 2500µs, with 2500µs providing maximum speed. The PWM frequency is set at 500Hz for reliable control.

Included

The package includes a DC micro metal gear motor with driver and one Gravity 3-pin cable, ensuring you have everything needed to begin your project.

Important Note

Please be aware that the embedded control chip consumes a small amount of input voltage, which may slightly reduce the motor voltage and speed. This is a standard characteristic of the design.
