Doubt in PMDC motor pulsed switching current
Found the problem...

The current which I am measuring is a Mosfet ON-Current, once the mosfet is OFF the current will be "free-Wheeled"..I should measure the current in the freewheeling path where i will get both ON-CURRENT &amp; OFF-CURRENT.Which will be a average current as expected..

for testing I have placed the resistor at freewheeling path at 180V+, and the current which I measured is the average current.
