Product Description

The 300 RPM Dual Shaft BO (Battery Operated) Motor is a lightweight, cost-effective gear motor designed specifically for hobbyist robotics and DIY science projects. Featuring a "Straight" body orientation, this motor utilizes an internal plastic gear train to provide a balanced 300 RPM output, making it ideal for fast-moving mobile robots. The unique Dual Shaft design allows you to mount a wheel on one side and a rotary encoder or a second wheel on the other, enabling precise speed sensing or enhanced mechanical stability. Encased in a durable yellow plastic housing, these motors are easily powered by standard AA batteries or a 9V battery, making them the go-to choice for student-led innovation.

Key Features

  • High-Speed Performance: At 300 RPM, this motor is optimized for speed-focused robots like line followers and remote-controlled racers.

  • Dual-Output Versatility: The protruding shafts on both sides offer flexibility for mounting encoders, specialized sensors, or dual-wheel configurations.

  • Low Current Consumption: Designed to operate efficiently on small battery packs, ensuring longer run times for portable robotic projects.

  • Lightweight Plastic Housing: Minimizes the overall weight of the robot chassis, allowing for faster acceleration and better maneuverability.

  • Easy Mounting Points: Features built-in holes for standard M3 screws, allowing for quick attachment to acrylic, metal, or 3D-printed chassis.

Technical Details

  • Reduction Ratio: 1:48 (Standard).

  • Wire Interface: Typically comes with pre-soldered 15cm leads or solder tabs.

  • Motor Shape: "I-Shape" or Straight.

Prototyping and Engineering Tips from Robogears

  • Voltage and Speed: While rated for 300 RPM at 6V, you can run this motor at 3V (lower speed/torque) or up to 9V (higher speed). Note that running consistently at 9V or higher will increase the wear on the plastic gears and significantly shorten the motor's lifespan.

  • Wheel Selection: These motors are perfectly compatible with standard 65mm Yellow Rubber Wheels. Ensure the wheel's center hole matches the "Double-D" flat shape of the motor shaft to prevent the wheel from slipping during high-speed turns.

  • The Importance of a Motor Driver: CRITICAL: Do not connect this motor directly to an Arduino or ESP32 pin. The motor draws more current than a microcontroller can provide, which will destroy the chip. Always use a motor driver like the L298N or L293D to control the speed and direction.

  • Sensing Speed (ODOMetry): Use the second shaft to attach a slotted encoder disc. When paired with an infrared speed sensor (LM393), your microcontroller can count the pulses to calculate the exact distance traveled or maintain a perfectly straight path.

  • Gear Protection: Plastic gears are susceptible to stripping if the motor is forced to stall (e.g., the robot hits a wall and the motor keeps trying to spin). Implement a current-sensing check in your code or use a physical bumper to stop the motor upon impact.

Package Includes

  • 1 x 300 RPM Dual Shaft BO Motor (Straight)

Disclaimer: This motor is designed for lightweight hobbyist robots. Do not use for heavy lifting or high-torque industrial applications. Avoid excessive side-loading on the shafts, as this can crack the plastic gear housing. Always ensure the polarity is correct for the desired direction of rotation.
