Hi all,

First thanks for your previous helpfull advices :) .

340V and 15V power supply work fine.


Now , third step in order to use my brushless milling machine, - I hope of course .....


I'd like to get advices from experienced members about the following draft; in fact , i got the initial drawing and replaced components.....

Surely mistakes,of course.....


A question about powering hall sensors:

In MC33035 datasheet, pin 8 ouput is 6,2 reference voltage for these items.

I added 5V power supply with 7805 for hall sensors ,and also for a power on led on casing, is this a good idea?


Second question:

What power needed for IGBT resistors, 1/2 ,1 or more watt?


Datasheet.zip is for MC33035 , MC33039 , FOD3120 and MEA1509SC

Schematic is the draft made with Kicad.

Numérisation0003-modif-1FINAL.jpg is the initial drawing.




Thanks a lot as usual.
