N20 DC Gear Motor Wheel 3PI miniQ Car wheel Tyre - 44mm

N20 DC Gear Motor Wheel (3PI miniQ Car Wheel Tyre - 44mm) is a compact, high-precision micro wheel engineered specifically for N20 micro metal gear motors and miniQ style robotic platforms. Featuring a 44mm outer diameter and a soft, high-grip rubber tire mounted on a durable plastic rim, it delivers excellent traction and smooth mobility in tight spaces. Its center hub is molded with a 3mm D-shaft hole that matches the output shaft of N20 gear motors, making it a staple component for mini line-following robots, micro maze-solvers, and small-footprint desktop rovers.

Features

• Compact 44mm outer diameter ideal for micro-robotics and miniature chassis designs
• Precision 3mm D-shaped center hub tailored for direct press-fit installation on N20 micro gear motor shafts
• Removable soft rubber tire with textured tread pattern for high surface friction and anti-slip operation
• Lightweight rim constructed from high-impact engineering plastic to minimize motor torque strain
• Perfectly suited for 3PI, miniQ, micro line-follower, and desktop autonomous robot platforms
• Provides precise speed control and low rotational inertia for rapid starting, stopping, and turning
• Simple press-fit design eliminates the need for additional hex couplers or mounting screws
• Highly durable construction resistant to wear on smooth indoor test tracks and wooden surfaces

Applications

• High-speed micro line-following and maze-solving competitive robots
• 3PI and miniQ style small-footprint autonomous smart car platforms
• Microcontroller-based mini rovers driven by Arduino, ESP32, or Raspberry Pi Pico
• Micro robotics platforms utilizing N20 micro metal gear motors
• Educational STEM kits, polytechnic diploma coursework, and university mechatronics labs

Important Notes:

• Designed specifically for 3mm D-shaft micro motors (N20 series); do not attempt to force onto 5.4mm TT motor shafts or standard round shafts.
• Align the flat side of the motor shaft with the flat internal edge of the wheel hub before pressing to avoid cracking or stripping the plastic center.
• Press the wheel onto the motor shaft evenly by hand; avoid using heavy tools or hammers which can damage the delicate internal gears of the N20 motor.
• Keep the rubber tires clean of dust, graphite, or oils using a damp cloth to maintain peak traction on smooth tracks.

Package includes

• 1 x N20 DC Gear Motor Wheel 3PI miniQ Car Wheel Tyre (44mm)
