The 60 RPM Dual Shaft BO Motor is a straight plastic gear DC motor designed to deliver reliable torque at low operating voltages. One of its biggest advantages is its ability to provide good torque output even when powered from 3V to 12V, making it highly suitable for battery-operated robotic applications.
This motor features a dual shaft design, allowing wheels or encoder discs to be mounted on either side. The small shaft size pairs perfectly with commonly available 69mm diameter wheels and 87mm multipurpose wheels for plastic gear motors, enabling an optimized and compact robotic drive system. Its lightweight body includes mounting holes for easy in-chassis installation, making it convenient for use in robotic platforms and embedded mechanical assemblies.
The BO series motor is a low-cost alternative to metal gear DC motors and is especially popular among students, hobbyists, and DIY robotics enthusiasts. It is widely used in small and medium-sized robot cars, including 2WD mobile robot platforms. Available typically in 60 RPM and 150 RPM variants, the 60 RPM version offers better torque with moderate speed, ideal for line followers, obstacle-avoiding robots, and basic autonomous vehicles.
Constructed using injection-molded plastic gears, the motor benefits from reduced manufacturing cost while maintaining consistent performance. The plastic gear mechanism offers low density and lightweight operation, resulting in lower inertia and smoother startup characteristics. These gears can absorb shock and vibration due to their elastic compliance, reducing mechanical noise and enhancing durability in small robotic systems.
Another advantage of plastic gears is their inherent lubricity, allowing operation with minimal or no lubrication. They have a relatively low coefficient of friction and offer corrosion resistance, eliminating the need for protective coatings or plating. The motor operates quietly compared to metal gear alternatives, making it suitable for indoor robotics projects.
Dimensional tolerances are generally less critical than metal gears because of the material’s resilience, which helps compensate for minor alignment variations. This also aligns well with the growing trend of using plastic housings and lightweight components in modern robotics and educational kits.
These motors are available in multiple colors such as yellow, black, and white. The color supplied may vary and is typically shipped randomly.
