230V Motor on a 120/240 line

I'm asking if it is OK to wire a 230V compressor motor to the 240 legs of a 120V line. I know about wiring to the L/N connections but what I need to know is if the 230V motor will NOT overheat on the 240V supply? The motor in the compressor will, of course, run intermittently, keeping the air supply pressure up to spec. At first, the motor will run for a long time, initially charging the system up to full pressure.
Will the motor run OK?
Thanks

240 volts is the nomenclature used for what you have. The motor will work just fine on 240 volts, as long as you wire it properly.

Voltage will not cause motor to over heat unless it is too low, causing the motor to work harder.
Most equipment rated at 230 volts on the nameplate will run fine on everything from 208 to 240 volts.

I kind of figured it was OK, just wanted a pro opinion to be sure.
Thanks all.
