wat happens wit a change torque

[sachinrivankar]

dear friends ,
i would like know that Wat happens to the motor wen d applied load changes.
how does it behaves, does it produce change in current, n can it b measured?
how??
can change in torque be made proportional to the change in current?

The mechanical power delivered to the load comes from the input electrical power. They are not totally related because the motor efficiency changes with load.

thanx friend,
but can u tel me, can i calibrate my circuit to measure the change in load.
wat r d circuit requirements wil b.??

You didn't even tell about the involved motor type. If it's an AC induction motor, I suggest a real power measurement to get
rid of of reactant current component, that's also sensitive to supply voltage variations.
