EE8005 Important Questions Special Electrical Machines
10 A stepper motor driven by a bipolar drive
circuit has following parameters: Winding
inductance = 30mH, rated current = 3A, DC
supply = 45V, total resistance in each phase =
15ohm. When the transistors are turned off,
determine the time taken by the phase current
to delay to zero and the proportion of the stored
inductive energy returned to the supply.
