Magnetic suspension motor
With the attention of Chinese people to health, now after 90 thermos cup began to soak wolfberry, from head to toe doping traces of health, which also makes the electric toothbrush this product popular up, electric toothbrush does not need too many skills, it can easily clean teeth. Compared with traditional manual toothbrushes, electric toothbrushes can remove plaque more effectively in a shorter time, reduce gingivitis, control calculus formation and pigmentation, reduce gum receding and neck tissue wear.
Moving toothbrush is so convenient, its core lies in the motor/motor. Xiaobian looked at some electric toothbrush brands with different prices on a large online shopping platform. Their description of the motor is "magnetic levitation acoustic motor" to promote
Conventional motors work on electromagnetic principles, converting electromagnetic energy into rotational energy. Maglev sound waves, on the other hand, work on a novel principle that uses ultrasonic vibration energy to transform it into rotational energy. When a conventional motor is running, we feel a noise because the internal structure of the motor vibrates at frequencies that are within the range that our ears can detect. The magnetic levitation acoustic motor is designed to vibrate at frequencies outside the range of the human ear, so when it is running we do not feel a sound, and therefore feel very quiet, which is a very important feature of the magnetic levitation ultrasonic motor.
