BZZZ! Ha. Now available from PMD Way are these fun and great value vibrating mini motor discs in packs of ten. Ideal for creating vibrating alerts or giving something small a bit of a shake. You can power them straight off 3~5V DC. If you're wanting to control them straight from a microcontroller output, put a resistor in series to drop the current draw to match your MCU's output. Or use an NMOSFET or NPN transistor to control them at full speed. Motors have adhesive double-sided tape fitted to the bottom to allow easy mounting in your project. Free delivery, worldwide. Specifications: Operating voltage: usually 3~5V DC Operating current: 60mA (3V); 100mA (5V) Speed up to 11000 RPM Weight: 1g Dimensions: Don't forget to check out our full range of robotics parts if this doesn't meet your needs.
