I apologize for the lack of TOPIC issue. (long time not posting here...) And I want to thank you all for your answers and useful links. I think now I have information enough to finish my motor controller design. I'd probably go with IR2010 drivers and IRFZ44 N-mosfets (that's what I can get in my city) plus some currents and temperature monitoring, PIC based. Thank you.
