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.
