7mm Waterproof Coreless Vibration Electronic Starter DC 1.5V5V Cylinder Vibrator Vibrating Engine Product overview A compact cylindrical coreless vibration motor designed for small electronics and hobby projects. Its 7mm diameter and waterproof construction make it easy to install in tight spaces where reliable vibration feedback or motion is required. The motor operates from DC 1.5V to 5V and uses an electronic starter for consistent startup. Key benefits Compact fit for tight spaces: 7mm diameter cylinder that installs easily in small housings and compact devices. Reliable startup and responsive vibration: coreless construction and electronic starter deliver fast response and consistent performance across the rated voltage range. Protected against moisture exposure: waterproof design reduces failure risk where occasional splashes or humid conditions occur. Wide voltage compatibility: operates on common small DC supplies from 1.5V to 5V for flexible power options. Simple integration: standard cylindrical form factor and twowire connection make it straightforward to add vibration feedback to prototypes and products. Main features Function: produces a compact vibrating motion suitable for haptic feedback, alert signals, or vibrationdriven movement. Voltage range: DC 1.5V to 5V for use with coin cells, singlecell lithium batteries, regulated USB supplies, or lowvoltage power rails. Size: 7mm diameter cylinder for minimal footprint in device designs. Design: coreless motor architecture for quick response and smoother operation compared with many conventional motors. Environmental resistance: waterproof construction for enhanced durability in damp or splashprone applications. Form factor: cylindrical vibrating engine with an electronic starter for consistent spinning from low voltages. Typical applications Wearable devices and handheld gadgets: provide discreet haptic alerts or confirmations in compact housings. Small robotics and toys: enable vibrationdriven motion, rumble effects, or balance adjustments in micro robots and toy assemblies. Consumer electronics and DIY projects: add vibration feedback to remote controls, gaming accessories, or custom electronics powered by 1.5V to 5V supplies. Installation and compatibility notes Power: match supply voltage within the 1.5V to 5V range for reliable operation. Drive: direct connection is possible for lowcurrent applications; for higher duty cycles or multiple motors, use an appropriate driver or transistor to manage current and switching. Mounting: small cylindrical footprint fits into narrow cavities; secure with adhesive or a retention bracket as needed. Environment: waterproof design improves resistance to moisture, but follow general goodpractice sealing and enclosure design for longterm reliability. This compact, coreless 7mm cylinder vibrator is suited for projects that require dependable vibration in small packages and variable lowvoltage power environments.
