ok, that's interesting information but it doesn't really answer my questions...

So I can charge my iphone, with the 61W macbook charger using the USB-C interface. I think the battery won't draw more effect than it needs/is dimensioned for, so this works fine. Can i use any charger with an USB-C interface to charge my iphone? or does it only work with apple products? Or...

Nobody is designing a battery charger. Its a question regarding some of the most important basic princples on how it works. If you google principles on inductive charging you will find videos explaining things in a asimple and basic way, that of course is not sufficient explanation on how...

ok so somewhat like pistons in an engine: first "piston" goes up, and the other piston down, and pushes the axle one way. Then the second piston goes up and the first down, pushing it the other way? The axle would have like a U-shaped horsewhoe at the end.

ok thanks so greater in diameter implies increasing the number of windings in the coil i guess?

OK, I am not really following, do you have an illustration, video or so on something similar in principle?

the goal is for the battery to charge faster. faster= better. But this must translate into technical specification changes of parts. So let omit all parts except for the reciever and transmitter coil. We assume all other parts can manage the increase (or has already been improved to do so) The...

No it has nothing to do with wheels. There's no purpose. The axle rotates like 90 degrees in one direction, and then it should rotate 90 degrees back to where it began. Thats the "requirement". Problem is that the motor only rotates in one direction, otherwise you could just drive the engine in...

it's a theoretical example. think of it as for educational purpose in a high school physics book or something. I am not redesigning my phone charger =) So youre saying to increase the charging speed - assuming the battery can manage you'd need to change ALL these parts: 1. have a "better"...

Goal: To have an axle rotate back and forth from one position to the other. We have a motor rotating in one direction How so solve this in a smart/simple way? I'm thinking having 1. one cog on the motor axle, rotating the same way as the motor 2. a second cog connected to the above cog that...

If charging some smaller toy, phone, electric razor, toothbrush or the like with induction charging I assume that the speed (time it takes to charge an empty battery) will depend on 1. the battery to some extent, but for this sake let's omit that 2. the inductive charging it self 3. wall socket...

yea i suspected that. but what do you have an oscillator for in an oral-B type of rotary motor toothbrush?

yea thanks I've seen these. But doesn't really answer my question of what these components mentioned above actually do and why they are needed.So i might have figured this out by myself what these components does. this is my hypothesis: AC voltage from power outlet is incresed in frequency by...

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. there's a couple of components there that i...

add 20% to time or effect?
