Product Description (Detailed):
Unleash the potential of your robotics and automation projects with our versatile 100 RPM Straight Single Shaft BO Motor, a reliable and cost-effective gear motor designed for optimal performance in diverse applications. This compact DC geared motor, often referred to as a "Battery Operated" motor due to its efficiency at lower voltages, offers a compelling balance of speed and substantial torque, making it ideal for everything from small mobile robots and DIY smart cars to educational platforms and intricate automation systems. Operating typically within a 3-12V DC range, this motor's integrated plastic gearbox ensures smooth power transmission and features a straight single shaft with a common 5.5mm diameter, compatible with a variety of wheels like 69mm or 87mm diameter options, simplifying integration into your designs. Its lightweight construction, pre-drilled mounting holes, and inherent low noise operation contribute to its user-friendliness, while the injection-molding process for its robust plastic gears provides durability, shock absorption, and resistance to corrosion with minimal maintenance. Engineered for consistent performance, this 100 RPM BO motor delivers a rated torque of approximately 1 kg-cm, alongside a low no-load current of 40-180mA, ensuring energy efficiency for battery-powered projects. Whether you're a robotics enthusiast, a student, or a professional developer, this motor provides the precise motion control and reliable power required for your innovative creations.
The 100 RPM BO Motor (Straight Single Shaft) is a compact, plastic-geared DC motor designed specifically for DIY electronics, robotics, and embedded systems projects. It provides a good balance between torque and speed, making it ideal for beginner and educational robots such as line followers, obstacle avoiders, and automated carts.
With a 12V operating voltage, this motor delivers approximately 100 rotations per minute under no load, suitable for lightweight tasks. Its single straight shaft allows easy attachment of compatible robot wheels, pulleys, or rotary encoders.
