12V 200 RPM Johnson Geared DC Motor – Grade B

The 12V 200 RPM Johnson Geared DC Motor (Grade B) is a powerful and reliable component, perfect for projects requiring a blend of high torque and moderate speed. This motor features a robust gearbox that significantly reduces the motor’s speed while multiplying its torque, making it an excellent choice for a wide range of mechanical applications. While rated as “Grade B,” this motor offers a cost-effective solution without compromising on core performance, making it a favorite for students, hobbyists, and robotic enthusiasts. It provides a consistent 200 RPM at 12V, which is ideal for everything from mobile robots to simple automation systems where precision and strength are key.

Key Features:

• High Torque Output: The integrated gearbox enhances the motor’s torque, allowing it to move heavy loads or overcome significant resistance.
• Moderate Speed: With a consistent output speed of 200 RPM at 12V, this motor is perfect for applications that need controlled, steady motion rather than high-speed rotation.
• Durable Construction: Built to last, the motor and gearbox assembly can withstand the rigors of various projects, ensuring long-term reliability.
• Versatile Voltage Range: While rated for 12V, you can also operate this motor at lower voltages (e.g., 6V) to achieve a lower speed and torque, offering more flexibility for your design.
• Easy to Mount: The motor’s standard design and pre-drilled mounting holes make it simple to integrate into chassis, frames, and custom builds.
