Vibration motor is a coreless DC motor and the size of this motor is compact. These motors are applicable for different applications like electric toothbrushes, wearable devices, massaging products, mobile phones, pagers, handsets, etc.
The main features of vibration motor is the magnet coreless DC motor are permanent, which means it will always have its magnetic properties (unlike an electromagnet, which only behaves like a magnet when an electric current runs through it); another main feature is the size of the motor itself is small, and thus light weight. Moreover, the noise and the power consumption that the motor produce while using are low. Based on those features, the performance of the motor is highly reliable.
