What type of motor used in electric toothbrush
Electric toothbrush usually uses micro small power drive geared motor, commonly used electric toothbrush drive motor by stepper motor, hollow cup motor, DC brush motor, DC brushless motor, etc.; this drive motor has the characteristics of low output speed, high torque, low noise, long life, etc.; mainly assembled by the micro drive motor, gearbox mechanism, the technical parameters of electric toothbrush motor is usually customized according to demand The technical parameters of the electric toothbrush motor are usually customized according to the demand and developed.
Electric toothbrush working principle: electric toothbrush is through the rapid rotation or vibration of the electric motor core, so that the brush head produces high-frequency vibration, instantly decomposing toothpaste into fine foam, deep cleaning teeth, at the same time, the quivering of the bristles can promote the blood circulation of the oral cavity and have a massage effect on the gum tissue. Electric toothbrush motor performance parameters on the brushing effect is not the same, the following electric toothbrush common drive motor.
