Full Product Description

Power Your DIY Creations with the Dual Shaft Worm Gear Motor

Have you ever tried building a custom motorized vehicle, only to struggle with aligning two separate motors to drive your wheels straight? It's a common frustration for makers and educators alike. We know that building the chassis should be fun, not a mechanical nightmare.

That’s exactly why this 3-6V Dual Shaft DC Gear Motor is a game-changer for hobbyists. Designed with an integrated worm gear reduction box, it provides synchronized power to both sides of your model simultaneously.

The Ultimate "Plug-and-Play" Drive System

Forget complex mounting brackets. You can instantly create a functional rear-wheel drive system by simply securing this gearbox onto a piece of wood, thick cardboard, or a plastic base plate using double-sided tape or hot glue. Just slide two 2.5mm bore wheels onto the extended 28mm shafts, connect your battery, and your custom vehicle is ready to roll!

Efficient Power, Impressive Speed

Whether you are building a lightning-fast mini RC car or a reliable pulley mechanism, this motor delivers. Operating seamlessly between 3V and 6V, it offers an impressive speed range from 700 RPM (at 90mA) up to 1300 RPM (at 120mA). This means you get a fantastic balance of high-speed rotation and low current draw, ensuring your batteries outlast your creative sessions.

Versatile Applications for STEM and Hobbyists

Beyond simple cars, this dual-shaft mechanism is perfect for driving mini tanks, operating custom belt drives, or powering miniature conveyor belts for school science fairs. Weighing just 21.7 grams, it packs highly efficient kinetic energy into an incredibly lightweight and compact form factor.

FAQ Section

Q. How do I attach wheels to this dual shaft motor?
A. The motor features a standard 2.5mm diameter round shaft. You can simply press-fit any plastic hobby wheel or pulley that has a matching 2.5mm bore directly onto the extended metal rods.

Q. Can I control the speed of this DC gear motor?
A. Yes! By adjusting the voltage between 3V and 6V (using different battery packs or a step-down converter), you can vary the speed from roughly 700 RPM to 1300 RPM. You can also use a PWM motor controller.

Q. Is this suitable for building a robotic tank?
A. Absolutely. While it drives both shafts at the same speed (meaning you can't use this specific motor alone for differential tank steering), it makes an excellent main drive motor for single-tread systems or synchronized conveyor belt models.
