Valentin,
Intersting what you post, but I still stand by my answer to the question:

please also explain me the effect of higher frequency say 120 hz. to 50 hz rated motor.

It is a common misconception that you take "a" motor and drive it through an inverter. You need a motor designed for inverter drive and (as you mention) in some cases even forced cooling.
