Hi
I want to use a PI controller to control a 3 Phase BLDC motor, to which power will be supplied using a dc battery.
However I am confused since in my case, a battery always gives constant voltage, so how and what should the controller be connected to?
Can you help me how to build a PWM circuit electronically for the 3 phase BLDC motor? On the internet I have found ways to build it using arduino, but I don't want to use an arduino. I haven't worked with it before.
