uxcell DC3V 14000RPM Vibration Motor Eccentric Rotating Mass Electric Micro Vibrating Motor 12mm x 20mm

Features? An eccentric rotating mass vibration motor (ERM) uses a small unbalanced mass on a DC motor when it rotates it creates a force that translates to vibrations. Developed for massaging products or required vibra-call on their mobile / cell phones. Then the vibration alerting is an excellent way to alert operators to an event. Miniature vibrating motors are used in a wide range of products, such as tools, scanners, instruments, GPS trackers, and control sticks. Vibration motors are also the main actuators for haptic feedback which is an inexpensive way to increase a product's value and differentiate it from the competition. Due to the fact that the turning of the off-center mass produces an asymmetric centripetal force, a non-zero centrifugal force is produced when the motor turns.
