Electric Toothbrush Gearbox

Electric Toothbrush Gearbox

Nowadays electric toothbrush is widely used by more and more people. Some people doubt that the electric toothbrush with such large power will cause harm to the teeth and gum. In fact, the electric toothbrush does no harm. However, it can be difficult for a newcomer to control the intensity.

Project Description

ZHAOWEI is experienced in the development of miniature gearboxes and has designed and developed a gearbox for the electric toothbrush. With the combination of a permanent magnet DC motor and a planetary gearbox, the miniature gearbox module has the advantages of compact structure and stable torque.

Advantages:

Deep cleaning
Save your effort

Traditional electric toothbrushes realize the rotation of the toothbrush through a DC brushed motor and a worm gear drive. However, due to the limitation of gear accuracy and transmission mode, the output torque and rotation speed are reduced as the force increases during the brushing process. ZHAOWEI got rid of the worm drive and the unreliable transmission method. We adopt a permanent magnet DC motor and a precision planetary gearbox structure, realizing a balance of output force and a constant speed.
