Product Description (Detailed):
Elevate your robotics and automation projects with the robust Johnson Geared Motor 10 RPM 12V (Grade-B), engineered for applications demanding precise, low-speed, and high-torque DC gear motor performance. This versatile motor, often categorized as a "Grade-B" variant, offers an economical yet reliable solution without compromising on the core functionality critical for heavy-duty tasks. Operating at a steady 10 RPM at 12V DC, it's perfectly suited for driving mechanisms that require controlled, powerful rotation, such as robotic arm movements, conveyor systems, winches, and omni-directional robot platforms. Its integrated metal gearbox ensures exceptional durability and efficient gear reduction, converting high motor speed into substantial output torque. Typically, these motors feature a side shaft design with convenient mounting holes for easy integration into various chassis and frameworks. While specific stall torque values may vary slightly between manufacturers for Grade-B motors, they consistently deliver ample power for challenging loads. Remember to pair this DC gear motor for robotics with a suitable motor driver (e.g., L298N) capable of handling its operating voltage and current requirements for optimal performance and protection. This reliable 12V DC motor is an excellent choice for hobbyists, students, and engineers looking for dependable power in their automated designs.
The Orange 12V 10 RPM Johnson Geared DC Motor is a low-speed, high-torque DC motor tailored for tasks that demand precision and power. With its rugged metal gearhead, it offers exceptional durability for continuous use in heavy-duty robotic platforms, miniature conveyors, smart locks, rotating bases, and automated systems.
Equipped with a rear shaft for encoder mounting, it supports closed-loop speed or position control when paired with a rotary encoder – making it perfect for Arduino, Raspberry Pi, or industrial microcontroller-based projects.
