DC12V N20 Geared Motor 30rpm 6V Gear Reduction Electric Motor For Robot Door Lock

The DC12V N20 Geared Motor with a 30RPM output speed is a compact, high-performance gear reduction motor ideal for precision control applications. Featuring a durable stainless steel gearbox and permanent magnet DC motor, this unit offers excellent torque output and smooth operation. The N20 gear motor is specifically designed for small-scale mechanical systems that require high torque and controlled speed, making it perfect for robotic arms, electronic door locks, smart locks, vending machines, and DIY automation projects.

The motor operates efficiently at DC 6V–12V, with an optimized reduction ratio that delivers stable rotational speed and reliable torque. At 6V, it delivers a typical speed of 30RPM and ensures consistent torque under load. This motor’s compact size and lightweight design make it highly adaptable for integration into limited-space environments. The 3mm diameter output shaft allows easy coupling with wheels, gears, or customized mechanical components.

Built with high-precision metal gears, this motor resists wear and ensures long service life, even under frequent usage. It also features excellent stall characteristics, allowing the motor to perform well under sudden resistance or uphill conditions. The low no-load current ensures energy efficiency, making it ideal for battery-powered devices.
