A brushed motor paired with an internal plastic gearbox that reduces speed to increase pulling power (torque). Its signature yellow housing is iconic in the maker community. The motor features a dual-sided output shaft, allowing you to mount the wheel on one side and a speed encoder disk (for distance/speed sensing) on the other. The included wheel features a high-traction rubber tire and a plastic rim with a "double-flat" center hole that press-fits perfectly onto the motor's shaft, ensuring no slippage during acceleration. Features: Plug-and-Play Design: The motor comes with pre-soldered wires (in most kits) or easy-to-solder tabs for quick assembly. Dual Shaft Versatility: Supports simultaneous wheel mounting and encoder attachment for closed-loop control. Interference Suppression: Most versions include an internal EMC (Electromagnetic Compatibility) circuit to reduce electrical noise that can interfere with microcontrollers. High Traction: The 65mm rubber tire provides excellent grip on flat indoor surfaces, allowing the robot to climb small inclines or navigate low-pile carpets. Wide Compatibility: Works seamlessly with common motor drivers like the L298N, L293D, or the XIAO/Arduino motor shields. Specifications: Gear Ratio: 1:120 No-load speed(3V): 50RPM No-load speed(5V): 83RPM Torque (3V): 0.8Kgcm Torque (5V): 1.0Kgcm Size: 69mm * 37mm * 23mm Internal Gear Material: Engineering Plastic
