100 RPM Dual Shaft Straight BO Motor Yellow Plastic Gear Motor for Smart Car Robot

Product Description The 100 RPM Dual Shaft Straight Battery Operated (BO) motor is the backbone of beginner and intermediate robotics. Often referred to as a "Yellow Gear Motor," it features a built-in reduction gearbox that converts high-speed DC motor rotation into a stable, high-torque output of 100 RPM. The dual shaft design is particularly useful, allowing you to mount a wheel on one side and an encoder disk on the other for precise speed and distance tracking, making it the perfect choice for line-following or obstacle-avoiding robots.

Key Features

• Dual shaft output for simultaneous wheel and encoder mounting.

• Lightweight plastic gearbox reduces overall robot weight for better speed.

• Broad voltage compatibility (3V to 9V) allows for various battery configurations.

• Standard mounting holes compatible with most DIY robot chassis.

• Cost-effective and durable for educational and prototyping purposes.

Prototyping and Engineering Tips from Robogears

• Driver Selection: Use the L298N or L293D motor driver modules to control these motors. They provide the necessary current and allow you to reverse the direction easily via your microcontroller.

• Speed Monitoring: Utilize the second shaft to attach an IR slotted optical encoder. This enables your robot to measure RPM and travel distance accurately (odometry).

• Power Supply: For the best performance, power these motors with 6V (4x AA batteries or a 2S Li-ion battery with a regulator). Running them at 3V will result in very low torque, which might not be enough to move a heavy chassis.

• Interference: Solder a 0.1uF ceramic capacitor across the motor terminals to suppress electrical noise that could interfere with your sensors or microcontroller logic.

Package Includes

• 1 x 100 RPM Dual Shaft Straight BO Motor
