Yellow Gear Motor for Smart Car Robot

 Yellow Gear Motor – Affordable DC Gear Motor for Smart Car & Robotics Projects

 Overview:

The yellow gear motor is a low-cost, compact DC motor with built-in gearbox, commonly used in Arduino-based smart cars, line-following robots, and DIY robotic platforms.

 Key Specifications:

• Voltage Range: 3V – 6V DC
• Typical Operating Voltage: 5V
• No-load Speed at 6V: ~200–300 RPM (varies by model)
• Stall Torque at 6V: ~0.8–1.2 kg·cm
• Current Draw: ~100–250 mA (no load), up to 1A (stall)
• Gear Ratio: Usually ~1:48
• Shaft Type: Dual output shafts with flat sides for easy wheel mounting

 Common Applications:

• 2WD or 4WD robot cars
• Line followers
• Obstacle-avoiding robots
• Bluetooth/WiFi-controlled vehicles

 Motor Driver Compatibility:

• Use with L298N, L293D, or TB6612FNG motor drivers for control
• Needs external power supply (battery pack or regulated power)

Tips:

• Use a rubber tire wheel with the flat shaft
• Add an encoder wheel or sensor for speed tracking
• Use a battery pack (e.g. 4xAA) for better performance
