Product Description

The 43mm Rubber Wheel Tyre is a premium movement solution specifically engineered for the N20 Micro Gear DC Motor. Designed for high-precision tracking and smooth navigation, this wheel features a specialised "D-axis" hub that ensures a non-slip, secure mechanical connection with the motor shaft. This 3PI MiniQ-style wheel is a favourite at Robogears for building compact line-followers, miniature sumo-bots, and educational smart car kits. The combination of a rigid plastic rim and a high-grip rubber tyre allows your robotic projects to maintain excellent traction on various surfaces, ensuring consistent movement and encoder accuracy.

Detailed Key Features

N20 Optimised Hub: Features a precision-moulded D-hole that fits perfectly onto N20 micro gear motor shafts, eliminating the need for set screws or external couplers.
High-Traction Rubber Tread: The outer tyre is made from a soft rubber compound designed to maximise friction on smooth surfaces, preventing wheel-slip during rapid acceleration.
Heavy-Duty Construction: Built with durable, high-impact plastic to withstand the stresses of robotics competitions and laboratory testing.
Compact Tracking Design: The 43mm diameter provides an ideal balance between ground clearance and torque, making it perfect for small-scale autonomous vehicles.
Encoder Compatibility: Optimized for use with N20 motors, supporting high-resolution tracking and position feedback for advanced navigation algorithms.

All Technical Details

Colour Profile: Features a professional Black & White aesthetic (White rim with Black tyre).
Mechanical Interface: Single-side D-axis bore for easy push-fit installation.
Rotational Accuracy: Balanced design to ensure smooth rotation at high RPMs, critical for consistent pulse counting in encoder-based systems.
Durability: Materials are chosen for their resistance to wear, ensuring the tire maintains its grip over many hours of operation.

Prototyping & Engineering Tips (Robogears Exclusive)

Shaft Alignment: When mounting the wheel at your Pimpri workshop, ensure the flat side of the N20 motor shaft is aligned with the flat edge of the D-hole. Push the wheel on firmly, but avoid excessive force that could bend the motor's gear assembly.
Cleaning for Traction: If the wheels lose their "tackiness" due to dust, simply wipe the rubber tyres with a damp cloth or a small amount of isopropyl alcohol to restore original grip performance.
Encoder Setup: If you are using these for a line follower, remember that the wheel's 43mm diameter dictates your travel distance per revolution ($C = \pi \times d \approx 135\text{mm}$); use this value to calibrate your PID loops.
Balanced Design: Ensure the wheels are pushed equidistant onto both motors to maintain a straight tracking path and prevent the robot from pulling to one side.

1 x 43mm Rubber Wheel Tyre for N20 Gear Motor (D-axis)
