Vibration Motor
The Vibration Motor creates haptic feedback through an eccentric rotating mass (ERM). Driven by DC voltage, it produces vibrations for notification systems, tactile feedback devices, and DIY massagers.
Key Features
- Eccentric mass design produces strong vibrations
- Small and lightweight for portable devices
- Low voltage operation (typically 2-5V)
- Simple 2-wire connection
- Fast startup response time
- Reliable brushed motor construction
- Low cost for mass production

Applications
- Mobile phone-style vibration alerts
- Haptic feedback for game controllers
- Notification systems
- Wearable device alerts
- DIY massagers
- Sensory stimulation devices
Important Notes
- Secure motor firmly – vibration will loosen mounting over time
- PWM can control vibration intensity (not just on/off)
- Startup voltage may be higher than running voltage
- Do not exceed rated voltage – will overheat and burn out
- Some vibration may be audible as buzzing sound
