This is a tiny round coin size vibration motor. Use it to provide vibrational alerts. It comes with a double sided tape on the bottom side which can be used to attach this motor to any flat surface. When powered, the vibration motor causes the attached surface to vibrate. This motor works with an input voltage as low as 2.5V and at higher voltages it vibrates like crazy! It has wire leads coming out from its body which can be used to solder the motor to a PCB.

This Flat 1034 Mobile Phone Vibrator Motor is a shaftless vibration motor that is fully-enclosed with no exposed moving parts. Its small size (10 mm diameter, 3.4 mm height) and shaftless design mean you can mount it on a PCB or even place it in a pocket to add quiet, haptic feedback to your project.

The motor has a 3M adhesive backing on it for easy mounting and 1.5″ leads for making quick connections. Polarity is not important; the motor can run CW or CCW.

This tiny, button-type, vibrating motor shakes with a vibration amplitude of 0.75g and draws approximately 60 mA when 3 V is applied to its leads.
