I have a Ingersoll Rand Compressor model# 2545E10V 10 HP,3 phase and I would like to convert it to a signle phase. would this motor here be good to go with and what other items will be needed to complete the single phase setup ? http://www.ebay.com/itm/L1510T-7-5-HP-1725-RPM-New-BALDOR-ELECTRIC-MOTOR-Air-Compressor/251853421650?_trksid=p2047675.c100011.m1850&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D28774%26meid%3Df177acca83bb4c07bd5176bc195c5550%26pid%3D100011%26rk%3D3%26rkt%3D10%26sd%3D200748486453

You need a single phase motor to do that. A 3 phase motor cannot be made to run on one phase.

Did you change the 3 phase motor out with a single phase motor? A 3 phase motor cannot be made to run on single phase.

Hi robles212
To convert your T-30 to single phase you will have to do one of two things.
1. Change the motor to a single phase motor
2. Buy and install a "Phase Converter" to convert 3 phase to single phase
Please rate me

Hi Omran,
The capacity of your compressor is 7.46 if the motor drive is 2 hp. 9.79 if the motor drive is 3 hp.


Hope i can help you.

According to the information you provided your looking at a 10 HP motor at three phase. Do you have three phase at your location? If not I would look into getting a single phase compressor. If you do want to get it going I would notify your local IR dealer so they can get you the right Model number, RPM, Pulley and Motor Frame Size to match your unit.

Please read below....Jim...if this helped you please send me a positive response...Thanks!

When you google home made 3 phase converters, you will find many ways to make use of 220v single phase instead, however you are limited as to the hp that the motor will produce. If you spin the motor first then apply 220v, the motor will continue to turn at much reduced hp. You need full power to turn a type 30 pump depending on pulley combination/ setup. Best to return the unit and get one that will run on 220v single phase. It will most likely consume more power to do the same work however it would cost a great deal to install 3 phase. Most likely not even available at all. Many years ago, I worked at Sears and happened to see an electrician coming down from roof access of building. He told me that sears had a 3 phase generator being turned by a 220v single phase motor to run an air conditioning unit. He said that it worked quite well. Does not sound cost effective.

check for loose wires..is the overload set right..should be around 16,,17amps

Does the motor rotate the compressor or just set there and hum? How old is this unit? Overload heaters may be to small or unit may be single phaseing. Is there air pressure in the tank when this happens.
