Hello everybody, new member here 
I am starting my first arduino shield, and a blog to document it, and i am looking for feedback & advices.
Thanks a lot in advance! (and sorry for my english, i'm from belgium)
Hello SebClerckx, that sounds like a great project. Is it intended for use with brushless DC motors, and if so, do you plan plan for sensorless or sensored feedback? Also, when it is for use with Arduino, I think it would great to have as many feedbacks to Arduino as possible, so in addition to current sensing; voltage, rpm and temperature would be great. I’m sorry I can’t give any technical advise, as I’m untrained in electronics and programming, but I’ll be following with interest. It seems to me that members of this forum is very generous in answering questions, especially if you keep it specific, and backed up with schematics, datasheets etc.
Good luck with your project!
Peter
Thanks for the first answer!
I plan to use a sensor, hooked directly to the arduino, to provide both speed and position feedback. Voltage might be a good idea too.
Sounds very interesting - I think you should flesh-out your design a bit more and then post again here
with some more detail - the functional diagram looks reasonable but the devil is always in the details!
Perhaps a starting point is to try and identify some part numbers for things like the inverter transistors
(MOSFET or IGBT?), current sensors.
Also work out the basic specifications of max voltage, max current, max drive frequency, PWM frequency
(if appropriate) and so forth.
