100 RPM 12V Centre Shaft DC Geared Motor High Torque Metal Gearbox Robotic Motor

Prototyping and Engineering Tips from Robogears

• Chassis Design: For a standard 2WD or 4WD robot, 100 RPM provides a "walking pace" speed. This is the sweet spot for indoor navigation, as it allows your sensors (like Ultrasonic or LiDAR) enough time to process obstacles and react before a collision occurs.

• Shaft Attachment: The 6mm shaft usually includes a flat "D-cut" or a threaded internal hole. When mounting heavy wheels, use a 6mm Hex Coupling with a set screw to prevent the wheel from spinning freely on the shaft during high-torque starts.

• Driver Selection: The L298N or L293D (with a heatsink) are excellent drivers for this motor. If you are building a precision rover, use a PWM signal to vary the speed, but keep the duty cycle above 20% to avoid stalling at low voltages.

• Maintenance: While the metal gears are rugged, avoid "hard-reversing" the motor (switching from full forward to full reverse instantly). Instead, use a short ramp-down period in your code to preserve the life of the gear teeth.
