I am trying to drive a 3 coil switched reluctance motor, like the one in the picture.
I wish to use it at speeds like 900, 1250, 1500 and 1800 rpm.
This means i have to calculate proper on and off miliseconds for coil1, coil2 and coil3.
How can i find out the proper values for each speed? I plan to drive them by means of tip120 darlingtons.
