R140 Small Brushed DC Motor – 3V-6V High-Speed Micro Hobby Motor for Arduino & Robotics

The R140 Small Brushed DC Motor is a highly versatile, compact, and efficient micro motor designed specifically for student projects, DIY hobbyists, and introductory robotics. Operating on a low voltage range of 3V to 6V, this lightweight motor delivers high-speed rotation, making it perfect for driving toy cars, mini fans, science fair models, and small automated mechanisms. Its dual flat-sided design makes mounting straightforward in narrow chassis compartments.

At Electrapac (www.electrapac.com), we source verified and reliable R140 DC Motors to ensure your electrical experiments and school STEM projects run flawlessly in Bangladesh.

Key Features & Benefits:

• Optimized for Battery Power: Runs perfectly on standard 2xAA battery packs (3V) or low-voltage DC power supplies.

• High-Speed Performance: Reaches up to 14,000 RPM at 6V input, delivering excellent velocity for lightweight propeller or wheel setups.

• Durable Carbon/Metal Brushes: Offers stable electrical conductivity and standard operational longevity for learning and testing.

• Compact Round Design: The standard 21mm diameter fits perfectly into universal toy motor brackets and plastic gears.
