(OP)
Can we use 400V-60Hz supply(Philippines)to feed 2hp motor (460V, 60Hz)?
Thanks.
Thanks.

Effectively, the rating of the motor reduces with the voltage.

How many leads out does your 460V motor have? If it has double-winding (230-series winding- delta connected), you could re-wire it to 230V- wye (parallel-230V, wye-connected) and supply 3-phase, 400V.
Can't do this with the usual 6-leads out (single winding) motor! Please try looking at the terminal box cover for a connection diagram and share it with us.

@ Marke:
So in order to make it work, when I test the motor, the load amps on the meter should be much less than the the one showed on the motor tag. Is this what you mean? if yes, what is the percentage.
Thanks everybody for the input.

From the Cowern papers on the Baldor motor web-site.

There are some 200/230/460 volt rated motors around, and some 208/230/460 Volt motors available. One of these may be a better choice.

Definitely an issue to consider.
Re Amps;
The amps will increase as the load increases. Generally you can run pretty close to rated amps. With the lower voltage the current will reach full load current with less applied load. The maximum torque will be less, but motors generally do not operate continuously at maximum torque. (With a few interesting exceptions.)
