Product Description
The RS PRO 420-621 Brushed Geared DC Motor is designed for industrial-grade, low-voltage applications where high starting torque and precise speed control are required. With its planetary gearhead architecture, this 42 mm motor delivers a maximum output torque of 2 Nm at an output speed of 67 rpm, making it especially suitable for demanding applications across industrial automation, laboratory setups, prototypes, robotics, water pumps, and camera positioning systems.
This DC motor operates on 12 V DC and is rated at 41.3 W, ensuring both efficiency and reliability in continuous use. The planetary gear system multiplies torque and stabilizes the output speed, while the sintered bronze bearings reduce friction, extend service life, and guarantee smooth rotational motion under load. The 8 mm diameter shaft, 20 mm long, provides a sturdy coupling interface for gears, pulleys, or direct connection to mechanical assemblies.
Built with an iron core and robust metal housing, the RS PRO 420-621 offers durability for both hobbyist and industrial environments, including manufacturing, automation, and laboratory apparatus requiring precise actuation. Its compact dimensions - 111.9 mm in length, 44.6 mm width and depth - allow easy integration into a wide variety of machinery and frame designs, while screw-type mounting provides secure installation.
The 104:1 gear ratio ensures substantial speed reduction and significant increase in torque, making the motor capable of driving heavy loads at controlled speeds. The 5.5 A current rating ensures compatibility with most low-voltage power supplies tailored for DC automation equipment. This motor is RoHS-compliant, guaranteeing adherence to environmental and safety standards.
Whether used in prototype development, water movement systems, robotics, automated conveyors, or custom industrial automation, the RS PRO 420-621 delivers consistent performance and long-term reliability, backed by RS PRO's quality assurance. Typical application sectors include industrial automation, laboratory automation, HVAC actuation, robotic drive systems, and custom automation equipment.
