I looked at the ENERPRO specs. It looks nice. But again, this is only a Gate-driver board only. What you need to build around that board are at least two loops: The outer loop voltage/speed regulator and its output goes to the lower current loop. Also you need at least two protections...

I don't know if this can help: 1)Winding losses, are the main losses: Irms^2 * Ra ( Irms = FF*Average current, FF (Form factor) for pure DC= 1, for six-pulse converter= 1.06 and for Single phase converter= 1.35, all of this Rule-thumb used at Reliance Electric) 4)Brush losses, rule of thumb is 1...

Hi to all, nice and interesting notes. You can break the problem in two parts to avoid mixing signals: 1)The control scheme and its implementation and 2)the power section regarding the BLDC. In the control scheme as electricuwe says, the inner and fastest loop is the current one. Over this loop...

First, you have to take in account that building a 6-scr DC drive is not a simple design. You need some means to limit-current such a current spillover circuit or a current minor loop. The output of this goes to the drive circuit. The drive circuit is somehow complicated since it has to...
