Default Generic Questions

Hello, a newb here and have a lot of questions of definitions like:

Lifted
Series Motors
Controllers
PDS
Etc…

I think I know what most of it means like Lifted means raising the ground clearance for bigger tires.

But things like Controllers and various motors are not quite making sense to this ole electrical engineer. For example upgrading from a stock 230 amp controller to a say 400 amps just is not clicking because the current to the motor is determined by the voltage applied and the impedance of the motor. For example if you have a 48 volt motor rated at 3 HP, the most current the motor can draw from 48 volts is 46 amps. The motor has 1 ohm fixed impedance. There is no way to force more current through the motor unless you step up the voltage from 48 volts.

So I guess what I am asking is there a web site that explains what is really going on so I can wrap my brain around it?

Step on the accelerator and see what happens!

Think EMF and CEMF. Not 1 ohm at rest.
