Hi,

If you want to learn about using Orcad or PSpice there is book available in the market. Basic tutorial for using this software.

Kunal,

You should have a .DSN file from Orcad that you want to post please or at least a .PDF for review.

Kunal,

I guess you do not have Orcad otherwise you should have a .DSN file.
Based on the .DOC file the circuit is an oscillator and gate driver.
I suppose if you get the osc to oscillate it will drive the motor at various speeds. There might be some coupling from the DC motor. Maybe add and RC filter into U1 supply.
I think you would do better using something like this:
http://circuits.linear.com/513
and use the LTSpice (which is free) to simulate your circuit.
