RE: what is the solutiom
Why is the line voltage low? Is it low only when you run the motor or is it low before you start running the motor?
Is the power supply big enough to supply the motor?
Did you get supplied with the wrong voltage motor and that's what you want to fix?
We need some hints before suppling answers.

Is this a DOL motor or do you have a soft starter or a VFD involved?

I would double check that the system you're connected to is in fact a 480V grounded wye. If it is, that voltage is cause for concern.
