Frequently Asked Questions
Q: What voltage should I use to power the 0408 micro vibration motor?
A: The motor is rated at 3V DC, which is the optimal operating voltage. It can also function across a range of 1–5V, making it easy to integrate into Arduino, Raspberry Pi, coin-cell battery, and other low-voltage DIY circuits without additional regulators.
Q: Does each motor come with an eccentric wheel?
A: Yes — each of the 5 motors in this pack includes an eccentric (off-center) wheel. Simply press the wheel onto the motor shaft to generate vibration output immediately. No soldering or extra hardware is required to get started.
Q: What kind of projects are these mini vibration motors best suited for?
A: These coreless brush motors are ideal for any project requiring compact, lightweight vibration actuation — including DIY handheld massagers, haptic feedback wearables, miniature toy vehicles, robotic grippers, STEM science kits, and Arduino-based prototypes. Their tiny 4×8mm form factor lets them fit almost anywhere.
