I know that you can switch phase 1 and 3, that's all I read, Can I switch phase 1/w/2 or 2/w/3 or this is going to hurt the motor life time or in other way?

Re: 3 Phases
Just thought i would add to what Jim had said:
Oil pumps, Hydraulic pumps, Or any equipment that uses a oil pump that is directional, IE. some refrigeration equipment. can be very badly damaged by reversing the motor.
So you might want to check with a phase rotation meter before applying power.

Re: 3 Phases
I draw a circle and place A at 3 o'clock, B at 7 o'clock, and C at 11 o'clock. This is your phasor diagram. Regardless of which phase you start with, follow it around this clock and you will know your rotation. If you make a change, this diagram will tell you if your rotation has changed.
