Key Features of N20 DC Gear Motor Wheel 42mm
- Perfect N20 Motor Compatibility: 3mm D-shaft bore ensures a secure, wobble-free fit on standard N20 gear motor output shafts without additional adapters.
- 42mm Diameter Sweet Spot: Large enough for smooth rolling and decent ground clearance, yet compact enough for mini-robot and micro-rover designs.
- Rubber Tread for Superior Traction: Textured rubber tire grips smooth floors, tabletops, and lightweight terrain - minimizes slipping during turns and acceleration.
- Lightweight ABS Hub: Keeps rotational inertia low so small N20 motors can accelerate and decelerate quickly, improving responsiveness.
- Press-Fit Installation: Simply push the wheel onto the D-shaft - no set screws, adhesives, or tools required for basic assembly.
- Balanced Construction: Precision-molded for minimal vibration at speed, ensuring smooth and quiet operation.
- 100% authentic from trusted robotics component suppliers
- Designed and sized specifically for the popular N20 micro gear motor family
- Ideal balance of compactness, grip, and weight for small-scale robotics
- Affordable pricing - buy individually or in bulk for multi-wheel builds
Perfect For
- Line-Following Robot: Pair two 42mm wheels with N20 gear motors and IR sensors to build a fast, precise line-follower for competitions.
- Bluetooth / Wi-Fi Controlled Car: Build a compact remote-controlled car using an ESP32 or Arduino with an H-bridge driver and two N20 motor-wheel assemblies.
- Maze-Solving Micromouse: The small form factor is ideal for micromouse robots that navigate tight maze corridors autonomously.
- Sumo Bot (Mini Class): Use four wheels for a stable, powerful mini sumo robot with aggressive traction on the dohy ring.
- Differential Drive Platform: Create a two-wheel differential drive base with a caster for learning PID control, odometry, and path planning.
- STEM & Classroom Kits: Perfect for educational robotics kits - students can quickly assemble and experiment with motor-driven vehicles.
- Conveyor or Feeder Mechanisms: Use the rubber-tired wheel as a friction roller in small-scale conveyor belts or paper/card feeders.
How to Use
- Identify the D-shaft: Locate the flat side of your N20 motor's 3mm output shaft - this ensures proper alignment.
- Align the Wheel: Match the D-shaped bore of the wheel hub with the motor's D-shaft.
- Press Fit: Firmly push the wheel onto the shaft until it seats snugly. No tools required for standard fitment.
- Secure if Needed: For high-vibration or high-torque applications, apply a tiny drop of cyanoacrylate (super glue) or use a small set screw if your hub variant supports one.
- Mount the Motor: Attach the N20 motor to your chassis using an N20 motor bracket (sold separately) and connect to your motor driver circuit.
- Test: Power the motor at rated voltage and verify the wheel spins true without wobble. Adjust seating if necessary.
