If your motor is 4.5kW using your method you would do the following:
4.5kW in Watts = 4500W
4500W / 3 = 1500W (This is where you divide the power of the motor by 3 for the 3 phases)
1500W / 230V = 6.52A (This gives you the current per phase)
6.52A * 1.1 = 7.15A (This applies the 10% for max operating current to flow without overload)
