C = common S= start R= run
You probably need a 5hp or 7hp motor. Look for HP rating o the 3 phase motor and select the same for single phase. 3 phase has same power but is more efficient at electricity use. Also consider a 3 phase converter. It allows a 3 phase motor to run on single phase service.
One uses single phase AC current (120/240), the other uses 3 phase AC current (most households will not have 3 phase in their home) One uses a 3 phase motor the other a single phase motor. 3 phase is usually used in industrial applications while single phase is used in home or small business apps.
Depending on who does the work it could be less expensive than getting a different air conditioner. The compressor will also need a capacitor and some rewiring. The old unit could have a 3 phase blower motor also which could run the price up even more. Although the changes can be made, the warranty at best will probably be a one year warranty and a new unit could have a 5-10 year warranty.
In electrical terms a three phase compressor is a compressor that is driven with a three phase motor. There are compressors that have three pressure heads. The three heads boost the pressure up in higher increments but these are referred to as three stage compressors.
You need to reverse the polarity of starting winding. You need to open the terminals. Get expert help.
by no of terminals.
The three letters commonly found on compressor terminal blocks are "R," "S," and "T." These letters represent the different phases in a three-phase motor system, with "R" indicating the first phase, "S" the second phase, and "T" the third phase. In single-phase applications, you might see terminals labeled as "L" for line and "N" for neutral instead. Proper connection to these terminals is essential for the correct operation of the compressor.
I would use a totally enclosed motor.

Single phase motor winding is often checked just by listening to the noise that the motor is making. An experienced person can tell if the motor is working at single phase or double phase.

No. That would be a single phase motor.

To use a single/one phase motor instead of a three phase motor is possible if you have a three phase power supply as you will only need to tap one of the three phases together with neutral and an earthwire, however to use a three phase motor instead of a single phase will require the provision of three phase power supply.
Just use any two of the three terminals that are available, this will give you a single phase capacitor.
First you have to have three phase power coming in. 3 phase are three hot wires working together on a syne wave. If you have 3 phase coming in, hook the three hot wires into the compresser, if it runs backwards, trade places with two of the wire and let the third one alone and you should be running.
