Brushless DC vibration motors (BLDC) has a stator, which is a permanent magnet, and a rotor, which is an electromagnet. The stator is stationary, while the rotor rotates around it. The motor uses a controller to switch the polarity of the electromagnet, which creates a rotating magnetic field. This rotating field interacts with the stator’s magnetic field to create a force that causes the rotor to vibrate.

The main advantage of BLDC vibration motors is that they can be precisely controlled, it requires more complex electronic commutator. And it does not have any brushes to wear out, that makes the BLDC motor more reliable, efficient and longer lasting than a brushed DC motor, because it does not have any brushes to create resistance.

BLDC vibration motors are typically used in applications that require high levels of vibration, such as cell phones and pagers. They are also used in some medical applications, such as massage chairs and blood circulation devices. BLDC motors are usually smaller and more efficient than other types of electric motors.
