  Hi,
  
  The desired load torque is applied to the motor by substituting a suitable value as shown in fig below:
  
  However, is it possible to apply this load torque by importing the data from an excel file?
  
  Can somebody please comment on this?

  You can import a two-column .csv file as a dataset, where the first column of data represents time and the second column is your waveform quantity of interest (load torque). Then, in the Load Torque input parameter box, you would define a piece-wise linear lookup function such as "pwl(torque_ds,time)". Here, "pwl" is the piece-wise linear lookup function (meaning that we will linearly interpolate for any time-steps between the provided data), "torque_ds" is the dataset, and "time" is the intrinsic variable that is used as the independent variable of the lookup table dataset. You can find out more about using expressions such as "pwl" and datasets in the Maxwell help. Another very useful expression is "pwl_periodic", which creates a periodic function based on a single period of input data.

  Thanks a lot for your assistance.
  
  The proposed methodology has worked.
