The Johnson Geared Motor (Grade B) 100 RPM is a robust and reliable DC motor designed for applications that require moderate speed and high torque. Here’s a detailed overview of its features, setup, and applications:
Key Features
Base Motor RPM: The motor has a base speed of 18000 RPM, which is reduced to 100 RPM through its gearbox, providing a balance between speed and torque.
Operating Voltage: It operates within a voltage range of 6-18 V DC, with a recommended operating voltage of 12 V DC.
Rated Torque: The motor delivers a rated torque of 5.5 kg-cm at 100 RPM, making it suitable for applications requiring significant force.
Stall Torque: The motor can handle up to 22 kg-cm of stall torque, allowing it to perform well under load.
Dimensions: The gearbox has diameter of 37 mm , shaft has a diameter of 6 mm and the shaft length is 30 mm , the motor has the dimension of 27 mm making it compact and easy to integrate into various projects.
Applications
Pan/Tilt Cameras:
Smooth Movement: Ideal for applications requiring smooth and precise movement, such as pan/tilt mechanisms in surveillance cameras.
Robotic Arms: Can be used to control the movement of robotic arms in automation systems.
Household Appliances:
Grills and Ovens: Used in automated grills and ovens for consistent and controlled motion.
Cleaning Machines: Suitable for use in various cleaning machines for precise and reliable operation.
Robotic Platforms:
Educational Robots: Widely used in educational robotics kits to teach students about motor control and automation.
DIY Robotics Projects: Perfect for hobbyists building custom robots and automation systems.
Coin Refund Devices:
Vending Machines: Commonly found in coin refund mechanisms in vending machines and other coin-operated devices.
Ticket Dispensers: Used in automated ticket dispensers for controlled dispensing of tickets.
Safety Precautions
Avoid Physical Contact: Keep hands and other objects away from the motor when it is powered to prevent injuries.
Check Voltage: Ensure the power supply voltage matches the motor’s specifications to prevent damage.
Regular Maintenance: Periodically check the motor and gearbox for wear and tear. Lubricate moving parts as needed and clean any dust or debris.
The Johnson Geared Motor (Grade B) 500 RPM is a reliable and versatile motor suitable for a wide range of applications, from household appliances to educational robotics. Its moderate speed and high torque make it an excellent choice for projects requiring precise and controlled motion.
Special Note
We are selling 2 types of Johnson Motors as “Johnson Geared Motor – Grade A Quality” and “Johnson Geared Motor – Grade B“, the only difference between them is the quality of materials used for manufacturing the motor. All other specification including look, dimensions, working etc. are same. The “Grade A Quality” motors shows slightly more torque count than “Grade B” Johnson Motors and hence dominates “Grade B” quality motors.
Shaft: The motor features a side shaft with metal bushes, enhancing durability and wear resistance.
Mounting: Equipped with six M3 mounting holes, the motor is designed for easy installation and secure mounting in your projects.
