Here is how it goes : I block the motor to reduce its rpm to a lower value than its no load rpm. I continuously watch/record its values as the rpm value reduces and attains a lower value. I only see a small 'packet'/'handful' of rpm values(intermediate values between no load and stable on-load rpm) displayed for like 5 to 6 times. Quite a few such packets were there. Ideally there should have been a series of reducing values differing each other by one, two or more units. So, on plotting the observed result( rpm --> time graph) I got an increasing curve which incremeted in steps(as one packet had same rpm values). Ideally one packet should only have two/three equal values and very few such packets should exist(may be one/two) so that the curve is smoother.
