RS PRO 420-722 is a brushed DC geared motor engineered for applications that require compact profile, precise low-voltage operation, and high torque transfer within automation, industrial, and model making environments. Designed with a planetary gearhead, this motor enables superior torque conversion while maintaining efficient speed reduction, offering 0.62 W power output when supplied with 3V DC.
This model provides a stable output speed of 195 rpm, ensuring reliable and repeatable positioning in robotics, custom mechanical devices, and other motion systems. With a maximum output torque of 61 mNm and a current draw of 450 mA, the 420-722 supports energy-efficient drive solutions even in limited space installations.
The robust construction features a 3 mm diameter shaft with an 11 mm length, fabricated from durable metal. The iron core motor and all-metal gearbox are reinforced by sintered bronze bearings, minimizing wear over extended cycles and ensuring smooth operation at full load. Its 64:1 reduction ratio and planetary design allow for increased load-handling capability while preserving precise rotational movement.
The motor mounts securely with screws and its enclosure measures 49.6 mm in length, 12 mm in both width and depth, making it suitable for integration into compact chassis or electrical enclosures. Its RoHS compliance assures engineers and project teams that the device meets essential environmental and safety standards for use in industrial automation, laboratory, educational and prototyping sectors.
Common industrial and technical uses include precision actuators in small machinery, positioning systems, robotic prototypes, and mechatronic assembly lines, where controlled low-voltage motion is essential. The planetary gear arrangement further ensures resilience under load, making the RS PRO 420-722 adaptable across automation, conveyor setups, and industrial test rigs.
