What motor does an electric toothbrush use?

Electric toothbrushes usually use micro low-power drive reduction motors. Commonly used electric toothbrush drive motors include stepper motors, coreless motors, DC brush motors, DC brushless motors, etc.; this type of drive motor has the characteristics of low output speed, large torque, and noise. It has the characteristics of low cost and long life; it is mainly assembled from a micro drive motor and a reduction gearbox mechanism. The technical parameters of the electric toothbrush motor are usually customized and developed according to needs.

Working principle of electric toothbrush: Electric toothbrush uses the rapid rotation or vibration of the electric movement to cause the brush head to vibrate at a high frequency, which instantly breaks down the toothpaste into fine foam and cleans deeply between the teeth. At the same time, the vibration of the bristles can promote blood circulation in the mouth. Circulation has a massage effect on the gum tissue. The performance parameters of electric toothbrush motors also have different effects on brushing teeth. The following introduces the commonly used driving motors of electric toothbrushes:
