Electrical- quick n easy
What are you using for your earth ground? You have a 220V motor so two wires will be hot and one will be the neutral. There will not be an earth ground unless you run a chassis ground off of the motor. If you have to buy cord anyway why not get the one with the extra wire and have the motor grounded?

Gotcha, I remember someone talking about using Romex which typically does not have the extra wire and assumed that is what you were going to use. I must have gotten my wires crossed.
There are 220V versions of Romex that do have 4 wires in the jacket.

SO cord, rated and used in various lengths for 480v 3ph motors. that'll do!
What Keith said, except...
Romex has solid conductors and will make a lousy drop cord (even temporary) for a compressor.
It's very rigid so any vibration is passed to the termination points. Its shape doesn't fit the cord grip connectors on the plug ends. And it's a PITA to terminate on the screw terminals.
Get some good SO or SOJW and a 20A plug and you'll be able to re-use it in the future.
