5mm Precision Planetary Gearbox Gear Stepper — 2Phase 4Wire Stepping Motor with Linear Screw and Metal Slider for DIY Camera Projects Why this module helps you Compact precision: the integrated 5mm planetary gearbox reduces backlash and multiplies positional resolution from the 2phase 4wire stepper, giving finer, repeatable motion for small actuation tasks. Smooth linear motion: the rotarytolinear conversion via the linear screw and metal slider provides controlled, lowplay linear travel ideal for camera focusing, small sliders, or microadjustment mechanisms. Durable construction: metal slider and screw components deliver stable mechanical performance and longevity compared with plastic alternatives. Key features and attributes Motor type: 2phase, 4wire stepping motor (stepping electronic starter configuration). Gearbox: precision planetary gearbox specified as 5mm, built to reduce backlash and improve step resolution. Linear mechanism: integrated linear screw and metal slider convert stepper rotation into linear motion for accurate positioning. Material: metal screw and slider for durability and stable mechanical response. Functionality: rotary stepper + gearbox → linear actuation; suitable for direct control with standard 2phase stepper drivers and controllers that support 4wire stepper motors. Form factor: compact assembly aimed at smallscale DIY and camera integration (reference size: 5mm gearbox element). How it solves common problems Replacing crude manual adjustments: provides repeatable, motorized control where hand adjustment lacks precision. Reducing backlash and jitter in small motion systems: the planetary gearbox minimizes lost motion and improves positional accuracy from each step. Compact integration for camera accessories: the combined motor, gearbox and screw slider simplifies mounting a linear actuator into small rigs without separate gearheads or leadscrews. Practical applications (use cases) DIY camera focus controller: mount to a lens or optical rail to achieve precise, motorized focus pulls for photography and videography projects. Micro camera slider or macro rail: integrate into small macro rigs to create smooth, repeatable linear motion for closeup shooting. Small automation and hobby robotics: use as a compact linear actuator for mechanisms that require accurate shorttravel positioning on DIY projects and prototypes. Compatibility and integration notes Electrical: designed for standard 2phase, 4wire stepper motor connections—compatible with common stepper drivers and controllers that accept 4wire stepper inputs. Mechanical: compact 5mm gearboxfocused design simplifies coupling into small assemblies; metal slider and screw require secure mounting to accept expected loading in smallscale applications. Ideal when your application needs a combined gearbox and linear actuator in a compact package suited for camera and hobby use. What to expect in operation Precise, incremental linear motion derived from stepper steps amplified by the planetary gearbox. Durable metal linear components for reliable mechanical travel and reduced wear. Straightforward wiring and control using typical 2phase stepper driver setups for microstepping or fullstep operation, depending on your controller. Note: This item is presented as a compact precision module combining a 5mm planetary gearbox, a 2phase 4wire stepping motor (electronic starter configuration), and a linear screw with a metal slider. It is intended for integration into DIY camera, small automation, and hobby projects where compact, repeatable linear motion is required.
