Answer / shyam

yes, we can run the IM above the 1500 RPM with variable
freqency device keeping the voltage constant at above the
rated voltage.but the life span of the motor may get
effected.

Answer / predator

Dear How is it possible, Because the company give the rated

means gradually damaged the motor's bearing, windings
thanks
