- FingerTech Gold Spark 16mm Gearmotor 50:1
- Features durable all-metal spur gears
- Ideal for mini-sumo and line-following robots
- Weighs only 28g, yet delivers substantial power
- Simplifies mounting with triple-supported 3mm shaft
- Supports up to 6.84kg-cm torque with precautions
The FingerTech Gold Spark 16mm Gearmotor 50:1 is an ideal choice for hobbyists and competitive robot enthusiasts, particularly in applications such as mini-sumo and line-following robots. This gearmotor features an all-metal spur gear reduction gearhead, paired with a Mabuchi FK-050 motor, ensuring durability and performance. The gearmotor is lightweight, weighing only 28 grams, yet it delivers substantial power, making it suitable for a variety of robotic applications.
The design includes an extra-long 3mm shaft that is triple-supported internally, allowing for direct wheel mounting. This feature simplifies the process of getting a robot operational. The gearmotor is compatible with a range of accessories, including Foam Wheels and Twist Hubs, which can be easily mounted. Additionally, it can be controlled via radio by soldering on a pair of tinyESCs.
For secure installation, the gearmotor can be mounted using 2-56 screws and custom motor mounts. For applications involving heavy robots or weapon systems, 3mm bearing blocks are available to support the shaft. Flat Motor Mounts are also offered for face-mounting in a panel.
Note: Operating the motor above 10V can decrease its lifespan, and exceeding a torque of 6.84kg-cm (95oz-in) may damage the output gear stage.
