Not sure if this is the right forum, but can anyone explain how the ev speed is controlled? I press the accelerator pedal and it goes faster. I have read “the motor demands more power” but no indication of how this is done.
On a toy, you would use a rheostat to control how much current get to the motor. That is not an option with an ev, so how does it work?
Edit: My thanks to all! I have some reading and learning to do now.
I recommend [https://www.youtube.com/watch?v=yEPe7RDtkgo](https://www.youtube.com/watch?v=yEPe7RDtkgo) — it is an excellent explanation of how to control the frequency and voltage supplied to the motor; and [https://en.wikipedia.org/wiki/Synchronous_motor](https://en.wikipedia.org/wiki/Synchronous_motor) and [https://howtomechatronics.com/how-it-works/how-brushless-motor-and-esc-work/](https://howtomechatronics.com/how-it-works/how-brushless-motor-and-esc-work/) explain how a synchronous motor works.
It is strange to think that in a few years, petrol technology will become a thing of the past, and only old folk will know what 2-stroke vs 4-stroke means, or turbo charging, or synchromesh, or idling … already starting handles, chokes, pinking and retardation are passing into oblivion.
