How Does an Electric Toothbrush Motor Work?
How it Works An electric toothbrush motor works due to an electric charge produced by a small battery in the toothbrush. Some electric toothbrushes work by inductive charging, which is when two parts of a transformer inside the brush are brought together and a small magnetic field creates an electric current to charge the battery. When the charge activates the motor, it creates a vibrating and oscillating effect, and a series of rods and receptors carries this motion all the way to the brush, causing it to spin. Other electric toothbrushes are operated by disposable, replaceable or rechargeable batteries. The electronic compartments of the toothbrushes are sealed to prevent water from seeping in and damaging the product. Effectiveness Research has actually shown that an electric toothbrush doesn’t work much better than a manual toothbrush. Even oscillating electric toothbrushes are only slightly more effective than regular brushes. One benefit of the electric toothbrush is the timer. T
