So i have a rough sketch of a toothbrush with its main components. Its like an Oral B type of toothbrush with a DC motor i think...that uses some type of camshaft and gears to create a back and forth rotation of the head from the revolving motor.
Theres a couple of components there that i don't know what they are doing and why they are needed:
Oscillator - it says it contains an oscillator but i haven't figured out what it does. Is it a part of the charger/base station? or part of the PCB in the toothbrush? but why is it needed? The "oscillation" of the brush is created mechanically from the rotating shaft through cams and gears (i think). So what does the oscillator do.
transformer - i thought induction chargers kind of where their own transformers... but do you have a transformer inside the charger/base station?
i mean you have a transmitter coil in the base station and a reciever coil in the toothbrush - that works like the transformer? or do you have an additional transformer before that?
also: if you want to charge faster What components do you change in order for it to charge faster? The coil in the transmitter or reciever or something else?
and I am not an electrical engineer so explain it simply please.
edit: Or have i misunderstood it - it might be one of these pulsating philips sonicare style brushes with a different type of motor that might be able to change its speed with varying input AC frequency provided by an oscillator?
