SMT vibration motors are made up of two main parts: the stator and the rotor. The stator is the stationary part of the motor and is usually made up of a permanent magnet. The rotor is the moving part of the motor and is usually made up of a coil of wire. When electricity is applied to the coil, it creates a magnetic field that interacts with the magnetic field of the stator. This interaction causes the rotor to spin, which in turn causes the vibration. Vibration motors are commonly mounted onto PCBs, or are soldered using a process known as ‘reflow soldering’.

SMT vibration motors are typically small and compact, which makes them ideal for use in portable electronic devices. For example, they are used in cell phones to provide haptic feedback (the vibrating sensation you feel when you press a button), which is a tactile sensation that can be felt by the user. They are also used in pagers, gaming devices, medical devices and many other types of electronic equipment. They are also relatively low power, which helps to extend the battery life of these devices.

There are a few different types of SMT vibration motors, including linear, piezoelectric, and eccentric rotating mass (ERM) motors.
