Hi, I've got a query about the circuit halfway down this page (the animated GIF):
Switched Reluctance Motor Drives Information
As I understand it - torque in the rotor is controlled by the rate of change in the field in the coil. Applying a voltage to the coil should result in a positive linear change in the coil's current, equating to a certain amount of torque.
Removing that voltage means the field will collapse very quickly, so producing an larger negative torque. (Assuming the rotor is at the optimum position, that is.)
What purpose then, does freewheeling serve? Is it to regulate the rate at which the field collapses?
-Any help would be greatly appreciated!
