N20 Motor Gearbox Long Shaft DC Motor 12v 100 Rpm DC Geared Motor For Actuator
The N20 Long Shaft Micro DC Gear Motor is designed for superior performance, durability, and precision. Built with high-quality metal gears and red copper components, it offers outstanding wear resistance and an extended service life. The internal copper coil ensures excellent electrical conductivity while reducing heat generation, delivering smooth and stable operation even during prolonged use.
This gear motor is available in multiple speed options — 20RPM, 24RPM, 50RPM, 60RPM, 80RPM, and 100RPM — allowing for flexibility across various applications. Despite its compact and lightweight design, the N20 motor provides high torque at low speeds, making it an ideal solution for space-constrained environments.
Engineered with fine craftsmanship, this motor excels in low noise, minimal energy consumption, and consistent output. Its key features — lightweight structure, high torque, low speed, long lifespan, and quiet performance — make it suitable for a wide range of applications, including smart toys, simulation robots, electronic locks, smart home systems, medical devices, and industrial automation.
We also offer custom design solutions to meet specific project requirements. Whether you need matching encoders, gearboxes, or motor drivers, our technical team is ready to provide tailored support. Contact us for more details and customization options.
