Hi. thanks for the reply. 

can you please elaborate a bit more on following points?

  1. When the switch of the braking resistor is open, will the winding be connected to a oltage source in externa circuit in maxwell? As per circuit theory, it should have a back emf source in open circuit and when the switch is closed for braking then that back emf should drive current in thw windings.

2. When external circuit is defined, how should the motion and excitation should be handled? I want that that rotor is rotating at some speed so there is induced emf in open circuit windings but when switch is closed, this will generate current in the windings and hence will brake the rotor also. How can i account for this chain of events in this simulation?
