CONSIDERABLE SHOUTING said:
Sorry Amber, it's sometimes pretty hard to accurately describe what I'm looking for in relation to the technology presented. I'm just saying this to get it off my chest now- I've been on this forum reading through builds for months because people kept saying it was the best way to understand electricity in relation to transportation, but I've asked hordes of times how I can learn more about motors/controllers/physics of electricity ect. and I've received no answer for anything. I'm basically putting together a puzzle without knowing what the picture's supposed to be.
well, it depends on what you're trying to learn, and what you already know, and how you yourself learn things. so we have to know what puzzle you're trying to assemble before we can specifically help with that.
Some filters you might consider, that may help you tell us what you' want to learn, helping us point you the right direction.
if you're trying to learn what stuff will do a particular job, a relativley easy way is to look at what others did that is like what you want to do, so you can do something similar, and so reading those kinds of threads works.
if you have a specific application for specific conditions, using things like http://ebikes.ca/simulator and the like willhelp you find the kind of system that will do the job.
that will also show you the interrelations between the various parts of the system, to show why you need x type of controller and y type of battery to power a motor of z type to perform a specific set of work.
if you want to know how specific technology works, that's a lot more general, and more or less helps to learn basic electrical first, basic electronics, then start learning about the specifc technology (controller, motor, battery, etc). which things to read depend on exactly what you want to know.
if you wnat to just know how one thing relates to another...the previous stuff is better.
if you want ot know in gneeral how a motor works, there's threads and wikipedia and gneeral internet pages about that, both for motors in general and for specific types of motors.
if you want to know in gneeral how a ocntroller works, same thing.
batteries, same thing.
if you want to know how to design these things from scratch, that gneerally requires a fair bit of technical background in that kind of technology, and then there are pages and threads about designing and building them, that will help learn what not to do (which is usually more important than just knwoing what *to* do).
and so on.
depending on wha tyou already know, and what you want ot learn, it may be more, or less, complicated than that.
I forgot about the DIYelectricCar site- probably because the damn thing looks like something I would have loaded up in Netscape when I was 8
. I'll head back there though, thanks for the tip.
i don't remmber what the forum looked like, but i do know it had a lot of good build info and also general explanations for all sorts of high power brushed stuff...just as much slogging thru things to find as there is here on es, but it's there.
So far what I somewhat "understand" with DC motors in racing is, once you start shoveling tons of amps into these DC motors- aside from internal resistance- there's nothing for the motor to do but spin harder and faster because the electrons have to go somewhere, and most of the improvements these teams do to the motors is dense copper rewinding (field strength? not sure yet), active cooling and heavily improved bearings to deal with the turning forces. Again however, all of this is just words to me right now, because I simply have never learned the basics and nobody has ever pointed me to a "motors and electrics 101" book outside of my own research.
there isn't a single place i know of that talks about all of them becuase there are so many differnet kinds, different methods of explanation dependign on both level of previous knowledge and level of desired knowledge, etc.
so, for instance, if what you want is practical knowledge of how to make a specific kind and type of motor better, that's different than wanting to know the science behind why that motor does what it does. sometimes knowing hte latter will help with the former, and sometimes it's irrelevant because you can just do what osmeone else already did to do the smae thing.
for a really basic thing you can simply start with basic electrical and electronic theory, at places like https://www.allaboutcircuits.com/education/
specifically
https://www.allaboutcircuits.com/education/category/motor-control/
but you'l have to tell us if that is understandable, or over your head, or stuff you already know, to know if that is useful to you or if you need a different resource.
