What size motor do you need to run a compressor 2 stage 80 gallon tank i have a 3 phase on it and want to change motor?

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.

What type of load is a 3 phase compressor motor?
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.
What are three terminals on a single phase compressor motor?
C = common S= start R= run
What should you do if a three phase motor or compressor is not rotating in the correct direction?
If your three phase motor runs backward, you have two phases swapped. double check a, b and c phase to find which ones are misplaced.
Can a single phase generator run a 3 phase air conditioner?
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.
How do you change a 3 phase 440 volt motor to a 3 phase 220 volt motor?
You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
Can you convert a 3 phase air compressor to 240 volts?
only way to convert from 3 phase to 240 would be to change the electric motor on the compressor

What kind of single phase motor would most likely be used to drive a refrigeration compressor?
I would use a totally enclosed motor.

You have one hp three phase motor where as available power supply is only single phase how can you run this motor?
You will need to install a phase converter or change the motor to single phase. You can find a licensed electrician at www.contraxtor.com
What happens if you change wires around on 3 phase motor?
It depends on how, and with what you change them.
Does the speed of a split phase motor change apporeclably with a change in the applied voltage?
no

Minimum breaker size 60 horsepower motor?
Need motor voltage, amperage and phase to give you an anwer.
Why does the fuse keep blowing when the compressor starts on a dual compressor package unit?
MOST LIKELY A COMPRESSOR SHORTED TO GROUND IF 3 PHASE. COMPRESSOR START PARTS OR SHORTED COMPRESSOR- SINGLE PHASE. COULD ALSO BE CONDENSER FAN MOTOR OR CAPACITOR ASSUMING IT STARTS WITH THE PRIMARY COMPRESSOR. WITH POWER OFF, CHECK WITH OHMMETER EACH COMPRESSOR LEAD TILL YOU FIND SHORT (LOW RESISTANCE READING). IF THREE PHASE, IT IS POSSIBLE TO REVERSE MOTOR DIRECTION IN AN ATTEMPT TO FREE UP A FROZEN COMPRESSOR (RECIP ONLY, NOT FOR SCROLL IN THAT THEY ARE ROTATION SPECIFIC). ONCE YOU GET IT GOING OR HAVE COMPRESSOR REPLACED, FIND OUT WHAT CAUSED FAILURE AND FIX IT. IT WILL JUST HAPPEN AGAIN IF YOU DON'T. THEY DON'T JUST WEAR OUT IF MAINTAINED PROPERLY. lc
