If speed is selected as mechanical input in specialized power electronics asynchronous block, option to specify inertia constant and friction factor will disappear. Then how to specify rotor inertia?

Select Torque TL to specify a torque input, in N.m, and change labeling of the block's input to TL. The machine speed is determined by the machine Inertia J and by the difference between the applied mechanical load torque TL and the internal electromagnetic torque Te. The sign convention for the mechanical torque is the following: when the speed is positive, a positive torque signal indicates motor mode and a negative signal indicates generator mode.
Select Speed w to specify a speed input, in rad/s, and change labeling of the block's input to w. The machine speed is imposed and the mechanical part of the model (Inertia J) is ignored. Using the speed as the mechanical input allows modeling a mechanical coupling between two machines and interfacing with SimMechanics and SimDriveline models.

Hi Karthik,
You could use the belt pulley block combined with an ideal torque sensor and an ideal velocity source:
You can use the rotational mechanical port of the induction machine and a combination of blocks from the Simscape multibody library. Please see image below and model attached (19b).
Additionally, you could also use blocks written in Simscape language. Please find more information in the link below:
For more examples, you could see Steve Miller's Simscape Multibody Multiphysics Library:
Hope it helps!
Bruno.
