hi
im doing a project on speed control of ac series motors using microcontroller preferrably AT89S8252 for an industry.
i.e. vary speed of the motor of the washing machine from 90 rpm to about 13000rpm..and vary direction also using h-bridges i guess.
im doing my msc electronics and we dont have 8051 in our syllabus. so im trying to do it on my own.plz send me some guidance.
my motor ratings -5.7A current max
winding resistance at 20 deg celcius.
tachogenerator-129ohm
field-1.1ohm
armature-1.33 ohm
plz help me and i will be very glad.
thank you
