And exactly why do you need a transformer ?

If you are trying to run a 240v motor on 120 by just using a transformer, you may find out there is too much current being drawn. What is the FLA on the motor tag?

Normal people just use the transformer the power company puts on the power pole. It can furnish 110V or 220V. (and other voltages for industrial buildings). Your compressor is most likely either 110V or

220V. Just install the proper outlet and use it.

The motor may be 120/240 but it doesn't have to be. You are really getting up to the limits of 120v with a 2HP motor. The one I have has a nameplate FLA of 15a and it took a whole lot more to start it. The NEC says a 2hp 120v induction motor is considered to be 24a. The one I had did pull more like that when loaded.

In a 1.5 phase system, you have 2 phases. One is real, the other chimerical.

Typically there is either a 1/4" spade connector you move or a plug you pull out and flip over. (for pumps and compressors) There are some other places where you just get the standard 6 wire motor and you have to sort out the wiring using the plate on the motor. That lets you reconfigure them all sorts of ways (120/240, CW/CCW etc) It also lets you choose the way you reverse it, with at least 2 choices (SPDT switch or 4 wire Drum switch). I usually see that with boat lifts.
