Hello everyone, I need a bldc speed controller for a motor which is requires 1.5k watt controller. I needed it for building my college project. I searched the controller online and all of those are costlier. Moreover I will not be using extra features given by them. So can anyone suggest me a speed controller diagram so that I could build myself one. That controller need to control bldc (doesn't have hall sensor) which is rated to run at 48v.
