To specify the load torque of the open stator coils induction machine, I was attaching a 'controlled torque' block at the what seemed to be the output terminal of the machine, as shown in the attached image. I assumed this was load torque in Nm units. I now have a feeling that this is incorrect, because:
a) When I view the electrical torque output, it settles at a different value at steady state. It is supposed to settle at the load torque value
b) When I give a negative value of controlled torque, the machine does not seem to go into generator action. I'm expecting an angle between 90 and 180 degrees between voltage across terminals and current through machine during generation.
Please guide me on how to proceed.
