Model: 12GPN30 planetary reduction electronic starter Compact planetary reduction starter designed for low voltage hobby and small automation projects. The N30 electronic starter delivers reliable low speed and increased output torque through its planetary reduction gearbox while remaining small and lightweight for tight installations. Key benefits Delivers increased output torque and controlled low speed thanks to the planetary reduction design, making it easier to drive gear trains and mechanisms from small motors. Compact dimensions and low weight allow installation in confined spaces and light assemblies without adding bulk. Wide operating voltage range improves compatibility with battery and low voltage power supplies, supporting flexible system design. Precision output shaft dimensions support secure coupling to common mechanical linkages and fittings. Main features Model: 12GPN30 planetary reduction electronic starter Size: 10 mm x 12 mm x 20 mm (N30 electronic starter) Output shaft diameter: 4.4 mm, cross shaft configuration Output shaft length: 3.7 mm Operating voltage range: 1.5 V to 5 V Weight: 9 g Function: planetary reduction for higher torque and stable low speed output Compatibility and usage notes Suitable for projects running on 1.5 V to 5 V supplies. Confirm motor driver or power source can provide adequate current for your load. Cross shaft output with 4.4 mm diameter fits common couplings and Dshaft style adapters; verify fit with your component dimensions before final assembly. Small footprint and light weight make this unit compatible with compact mechanisms where space and mass are limited. Typical applications Miniature robots and micro mobile platforms that need higher torque at low wheel speeds for better traction and control. Precision hobby mechanisms such as camera pans, gimbals, and servo replacements where compact, reducedspeed actuation is required. Small automatic devices and toys where compact size and low voltage operation simplify integration. Why choose this model The 12GPN30 combines a planetary reduction gearbox with a compact N30 starter form factor to provide a practical solution for projects that require reduced speed and increased torque without sacrificing space. Its defined shaft dimensions and wide voltage compatibility make it straightforward to integrate into custom assemblies.
