Micro Metal DC Geared Motor with Lead Screw (6V 98RPM M3*20)

Micro Metal DC Geared Motor with Lead Screw (6V 98RPM M3×20) integrates a precision M3×20mm threaded rod directly onto the gearbox output shaft, enabling compact linear motion from a rotary drive system. The miniature gearmotor operates at a rated 6V and delivers a no‑load speed of approximately 98RPM, translating to about 1.1mm/s linear travel when used as a lead‑screw actuator. Such a compact motion component suits small robotics mechanisms, precision positioning structures, and lightweight automation assemblies where space efficiency and controlled movement are essential.

Integrated Lead Screw for Linear Motion

An integrated M3 threaded rod converts rotational motion from the gearbox into smooth linear displacement without additional transmission parts. This built‑in lead screw design simplifies mechanical assemblies and reduces alignment issues commonly encountered with external couplers. The miniature actuator configuration supports compact robotics mechanisms, micro lifting systems, sliding structures, and experimental motion platforms where reliable short‑stroke linear movement is required.

Stable Low‑Speed Gear Reduction

A 1:150 reduction gearbox provides controlled rotational output suited for precision movement tasks. With a no‑load speed of 98RPM and a loaded speed around 60RPM, the micro gearmotor delivers steady motion while maintaining reasonable torque capability for small mechanical loads. Such gearing characteristics enable accurate positioning and smooth actuation for miniature mechanical designs, small automation prototypes, and experimental electromechanical systems.

Flexible Mechanical Mounting Options

A brass faceplate incorporates two threaded mounting holes designed for M1.6 screws (1.6mm diameter, 0.35mm pitch), supporting secure integration into compact mechanical frames. Additional compatibility with a dedicated mounting bracket or the extended mounting bracket provides extra installation flexibility while enclosing exposed gears for improved protection and structural stability in robotics or motion control assemblies.
