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.

Technical Details

  • Operating Voltage Range: 3.0V – 9.0V DC

  • Rated RPM: 100 RPM at 6V DC

  • No-Load Current: ≤200mA

  • Stall Current: ~600mA (at 6V)

  • Reduction Ratio: 1:48

  • Output Shaft: 5.5mm flattened (D-type)

  • Operating Temperature: -10 to +50 degrees Celsius

  • Dimensions: ~70mm x 22mm x 18.5mm

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
