Can you operate a 480 v 3 PH motor on 220 v 3 PH?

Most 3ph Motors are rated for both voltages. High Voltage Wiring (440-480) Connections goes as follows L1=>T1,12 L2=>T2,10 L3=>T3,11 4=>7 5=>8 6=>9. Low Voltage (220-240) goes as follows L1=>T1,6,7,12 L2=>T2,4,8,10 L3=>T3,5,9,11. "L" Denotes Line Side Voltage (Power Coming to the Motor) "T" Denotes Terminal Motor Leads. You may not have #10, 11,or 12 leads as most motors since the 1980's have been internally wired inside the windings to T1, T2, and T3 or 1, 2, and 3 which are the same wires. Usually the Junction box on the side of the motor has this already listed under it's cover. If it shows a Low and a High Configuration, you have a Dual Voltage Motor.
