Micro Metal DC Geared Motor with Long Shaft (6V 98RPM M3*25)
Introduction
Micro Metal DC Geared Motor with Lead Screw (6V 98RPM M3*20) combines a compact DC gearbox with an integrated M3 threaded lead screw, enabling direct conversion from rotary motion to linear movement without additional transmission parts. The miniature linear drive unit operates at a rated 6V and delivers a no‑load speed of 98RPM through a 1:150 reduction gearbox, providing stable motion and increased torque for compact mechanisms. A brass faceplate with threaded mounting holes supports precise installation, while compatibility with a dedicated extended mounting bracket allows secure enclosure of exposed gears for safer integration in robotics and mechanical assemblies.
Integrated Lead Screw for Direct Linear Motion
This compact gearmotor integrates an M3 threaded rod as the output shaft, allowing rotational output from the gearbox to drive linear displacement directly. The built‑in screw mechanism simplifies motion system design by eliminating separate lead screws or couplers. Such a configuration supports compact linear actuators, miniature push‑rod mechanisms, sliding platforms, and small robotic linkages where limited space and reliable motion transmission remain critical.
High Reduction Ratio for Stable Torque Output
A 1:150 gearbox reduction significantly increases output torque while maintaining controlled rotational speed. With a rated operating voltage of 6V and a no‑load speed of 98RPM, the miniature geared actuator delivers consistent performance suitable for precision mechanical motion. Load torque reaching 550g*cm and locking torque up to 1000g*cm enable reliable operation in lightweight lifting mechanisms, positioning systems, and small mechanical automation assemblies.
Compact Mounting Structure for Mechanical Integration
The gearbox front plate uses durable brass construction and includes two M1.6 threaded mounting holes (1.6mm diameter, 0.35mm pitch) for secure installation. Compatibility with dedicated mounting brackets allows enclosed gear protection while improving mechanical stability. Such mounting flexibility simplifies installation within compact robotics structures, miniature mechanical prototypes, and embedded electromechanical systems.
