34mm Mini Car N20 Motor Rubber Small Wheel

34mm N20 Motor Rubber Wheel – 3mm D-Shaft Mini Robot Wheel

Product Description

The 34mm N20 Motor Rubber Wheel is a compact and lightweight drive wheel designed specifically for N20 micro gear motors. It features a 3mm D-shaped bore for a secure press-fit connection with compatible N20 motor shafts, making it suitable for small robotic platforms and DIY mobile projects.

With a 34mm diameter and 6.5mm width, the wheel provides a good balance between compact size, traction, and movement speed. The high-grip rubber tire helps provide reliable traction on suitable indoor surfaces, while the lightweight 3.2g construction reduces the load on small N20 motors.

The wheel is ideal for mini-sumo robots, line-following robots, small RC cars, soccer robots, educational robotics, and compact IoT mobile platforms.

Working Principle

The wheel is designed to connect directly to a compatible N20 motor with a 3mm D-shaped shaft. The D-axis design provides a secure mechanical connection and helps prevent the wheel from slipping during operation.

When the N20 motor rotates, the wheel transfers the motor’s rotational movement to the ground, allowing the connected robot or vehicle to move forward, reverse, and turn.

Product Disclaimer

Product images are shown for illustrative and representational purposes only. The actual wheel may vary slightly in colour, tread pattern, hub appearance, dimensions, or other visual details depending on the manufacturing batch.

The N20 motor, chassis, battery, controller, motor driver, and other accessories are not included unless specifically mentioned in the package contents.

Important Notes

Motor Compatibility

The wheel is designed for compatible N20 motors with a 3mm D-shaped shaft. Please verify the motor shaft dimensions before installation.

Installation

The wheel is designed as a tight press-fit. When installing it onto the N20 motor, support the rear of the motor gearbox to avoid applying excessive axial force that could damage the internal gears.

Traction

Actual grip and performance depend on the surface, robot weight, motor torque, and operating conditions.
