If you have a frequency converter, you wreck the V/Hz relation. So you get the core of stator to saturated zone and has been hot. and your speed increased but in finally your stator winding has been failed. But now my doubt is if the motor is a 60 Hz rated and runs on a 50 Hz and run for a long time.. anything will happen.

Everything that has been said about V/Hz being constant for a frequency converter. Motor can operate at 60Hz 460V without much trouble, however only if the load remains at same HP (KW) from 50Hz operation point. Since this seems to be a centrifugal pump, the load torque will increase at square of the speed increase. So, can the load be controlled and limited? The motor nor the motor speed determines the load. The Load determines the Load. If you apply the same load at 50Hz or 60Hz the Load stays the same. Power is Power!

A 50/60Hz frequency converter has a iron core which have very poor performance at higher frequencies. So there for you want to keep the frequency as low as possible. Another thing with low frequency is that you get low losses in the semiconductors.
That is the reason the transformer-less solution have a rather low frequency. But on the other hand you want to have a high frequency to scale down the output filter.
