10PCS Micro Vibration Motor — Tiny Coreless Vibrator 4 x 8 mm, DC 3V / 3.7V Compact, reliable vibration modules for repairs, prototypes and small electronic projects. These micro coreless motors deliver tactile feedback and vibration in the smallest housings, making them ideal for handheld electronics, wearables, toys and robotics. Key benefits Small form factor: 4 x 8 mm dimensions fit into tight spaces where standard motors cannot. Ready for projects and repairs: pack of 10 provides spare units for testing, prototyping or multipledevice replacement. Responsive coreless design: coreless construction reduces rotor inertia for faster start/stop response and smooth vibration behavior. Appropriate for lowvoltage systems: designed for DC operation at approximately 3 V to 3.7 V, compatible with common small battery voltages. What this motor solves Restores vibration to devices where the original micro motor failed (phones, remotes, wearables). Adds tactile feedback to prototypes and small products without redesigning the enclosure. Supplies multiple identical units for batch testing or multipoint installations. Key attributes Quantity: 10 pieces Type: Micro vibration motor, coreless Size: 4 x 8 mm (diameter x length) Rated voltage: DC 3 V to 3.7 V Form factor: Tiny cylindrical vibrator suitable for compact assemblies Usage: Motor parts for replacement, prototyping, small electronics Performance and handling notes Operate within the specified voltage range for expected vibration strength and motor longevity; avoid sustained overvoltage. Coreless design offers quick, smooth vibration and efficient response compared with some traditional small motors. Mounting and electrical connection depend on your device design; use appropriate adhesives or brackets and proper soldering/wiring practices for reliable installation. For longer life, run intermittently rather than continuously when possible and avoid mechanical overloading. Typical use cases Smartphone and remote control : wornout vibration motors in compact consumer electronics that require a 4 x 8 mm vibrator rated around 3 V. Wearable devices and fitness trackers: Add or restore haptic feedback in bands, clips or other small wearable enclosures where space is limited. Small robotics and DIY electronics: Integrate tactile alerts or vibration feedback into microrobot projects, miniature toys, or custom IoT prototypes. Compatibility suited for applications designed for a 4 x 8 mm micro vibration motor and powered by DC 3 V to 3.7 V sources (coin cell packs, single Liion cells, or regulated 3 V supplies). Use as direct replacements where the physical size and voltage rating match the original component. What's included 10 x micro vibration motors (4 x 8 mm, coreless, DC 3 V–3.7 V) Precautions Confirm polarity and voltage before connection. Do not exceed recommended voltage. Keep away from strong magnetic fields and excessive mechanical shock. Follow standard ESD and soldering precautions when integrating into electronic circuits. These 10PCS micro vibration motors offer a compact, efficient solution for adding or restoring tactile feedback in small electronics and prototypes without changing system voltage or enclosure design.
