2PCS Vibration DC Electronic Starter with Eccentric Wheel — DC 3V–3.7V Small 030 Vibrator for Toy Model Add reliable tactile motion to small models and toy projects with this pair of compact 030 vibration motors. Each unit features an eccentric (offcenter) wheel that converts rotary motion into consistent vibration, optimized for lowvoltage, batterypowered applications. Key benefits Adds realistic vibration and tactile feedback to toy models and miniatures. Lowvoltage operation (DC 3V–3.7V) makes it suitable for common battery supplies and small electronics. Compact 030 size fits into tight spaces and lightweight assemblies without significant weight penalty. Sold as a pair (2PCS) to support multipoint vibration effects or spare/backup use. Main attributes Quantity: 2 pieces. Model/Size: Small 030 vibrator motor. Drive: DC operation at 3V–3.7V. Vibration method: Eccentric wheel (offset mass) mounted on the motor shaft. Intended use: Designed for toy models and small DIY projects requiring vibration or rumble effects. Integration: Simple twowire connection to a DC power source; suitable for direct battery connection within the specified voltage range. How this solves common problems Lack of movement or feedback in models: Provides tactile and audible vibration to simulate engines, impacts, or machinery. Limited power options: Operates at low, safe voltages common to small battery packs, avoiding complex power conversion. Space constraints: The small 030 form factor is designed to fit compact assemblies where larger motors cannot. Example applications 1) Model vehicles and trains — simulate engine vibration or road feedback in toy cars, trucks, and locomotives. 2) Miniature robots and moving dioramas — add rumble and motion effects to small robots, animatronics, or display pieces. 3) Handheld controllers and DIY gadgets — provide simple tactile feedback in custom controllers or novelty devices that run from 3V–3.7V supplies. Usage notes Operate the motors only within the specified DC 3V–3.7V range to ensure expected performance and longevity. Mounting should secure the motor body while allowing the eccentric wheel to rotate ; fastening methods vary by project. Each motor requires a basic twowire connection; polarity determines rotation direction and resulting vibration orientation. This 2PCS set provides an affordable, compact solution for adding vibration effects to toy models and small electronic projects where lowvoltage operation and minimal space are important.
