3 Volt ~ 6 Volt DC Yellow TT Dual Shaft Gear Motor for Robot Wheel

3V - 6V DC Yellow TT Dual Shaft Gear Motor is a widely used, high-torque plastic gear motor designed for hobbyist robotics and smart car chassis setups. Featuring a dual-ended D-shaft (TT shaft), it allows makers to mount a wheel on one side and a speed encoder disc on the other side for precise rotational velocity tracking. With its built-in reduction gearbox, low operating voltage, and lightweight structure, this motor provides optimal torque and speed balance when powered by standard battery setups or motor drivers like the L298N, L293D, or TB6612FNG.

Features

• Dual-ended output shaft (TT D-shaft layout) supporting simultaneously mounted wheels and photo-interrupter encoder discs
• Built-in high-efficiency spur gear reduction set delivering high torque at low rotational speeds
• Wide operating voltage range (3V to 6V DC), ideal for 2x AA, 4x AA, or single/dual 18650 battery power supplies
• Compact, lightweight high-impact plastic housing designed for effortless mounting on acrylic or metal chassis
• EMI/RFI noise reduction EMC magnet design for stable microcontroller operation
• Standard double-flat output shafts compatible with standard 65mm yellow robot wheels
• Pre-molded mounting holes for secure attachment using standard M3 machine screws
• Fully compatible with standard H-bridge motor driver modules (L298N, L293D, mini MX1508)

Applications

• 2WD and 4WD autonomous smart robot car chassis (Arduino, ESP32, ESP8266, Raspberry Pi)
• Line-following, maze-solving, and obstacle-avoiding mobile robotics platforms
• Speed-controlled mobile rovers using optical encoders and slotted disc sensors
• Bluetooth, Wi-Fi, NRF24L01, or IR remote-controlled DIY toy vehicles
• Microcontroller-based educational STEM projects, polytechnic diploma coursework, and university engineering labs

Important Notes:

• Soldering wires onto the motor terminals should be done quickly with medium soldering iron heat to prevent melting the adjacent plastic housing.
• Do not mechanically stall or block the output shaft while high voltage is applied; stalling the motor causes current surges that can burn out motor driver ICs or strip internal plastic gears.
• Solder a 100nF (0.1µF) ceramic capacitor across the motor terminals to suppress high-frequency electrical noise that could trigger unexpected microcontroller resets.
• Always drive this motor using a proper H-bridge motor driver (such as L298N or MX1508); connecting it directly to a microcontroller GPIO pin will destroy the chip's output pin due to excessive current draw.
