Yes. It will make your motor a little faster though, so it depends on what you are powering with this motor. IE Can the piece of eguipment be ran faster?
no you cant , dont even try it.
60hz will make the 50hz motor run faster than it was designed for , damaging all the internal parts and the coil.
no
It will not work at all.
cable size for the 90kW motor is 3CX150sqmm aluminum cable
What effect will be there on the motor (Induction) output power when a 100kW 50hz motor is connected to a 60hz power supply.
no
100

Should work at nearly full power as long as the polarities of the 4 pin plug are in sync and it is a 3 phase 50Hz motor. Do a regular temperature check under full operating conditions for the first hour to ensure speed is enough for cooling.

I know that a company named TEMco makes a 380v to 120/208 transformer. You can try contacting them for your specific application I will attach their website for you.
Generally this will be possible. To keep the motor energized correctly you need to keep the volts per hertz roughly at nameplate (so 7.6 volts per 1 Hz). 460/60 = 7.66 volts per hert. I would still verify with the motor manufacturer that it is OK to use in the fashion you are planning, though.
One way would be to hook it up to a supply (by itself, with no load) and measure the speed with a contact tachometer. If your supply is 60Hz, and the motor speed corresponded to one of the standard motor speeds, it would be a pretty safe bet you had a 60Hz motor. If the speed was about 20% faster than a standard speed, the motor is probably a 50Hz motor. Or 20% slower if you were running a 60Hz motor on 50Hz For instance, a 1750 RPM 50Hz motor would spin at about 2100 RPM if you ran it on 60Hz.
It is an extremely expensive way of utilizing the deep fat fryer. You should look into changing the heating coils in the fryer to utilize the new voltage. That said it can be done.
