Unfortunately, I am not 100% certain this is posted in the correct segment of the site. A phase compressor generally refers to a large air compressor used by contractors and the like to power various tools on a job site (nail guns, etc.).
If you are referring to a phase change compressor (and this is just a brand I am unfamiliar with) most of these have an internal power unit. Some do mount to your PC, but most are powered off a 110V line you will plug in independent of the rig itself.
Is this compressor for extreme overclocking? Or is this for power tools?

Have a Gardner Denver Electra Saver 2 compressor and it is not getting power to the control unit to start?


Is this something new you just installed? Is it not getting electrical power to junction box? If your getting 220 volts of power to unit is there a reset button or reset protocol? Thank you Sylvia and good luck. Make sure breakers are on. Please consult an electrician to obtain your power issue.

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...


It might. Mounting holes match? Shaft diameter and adapter match? Power supply sufficient for 5HP motor? It's a big motor! You might get a better answer from the ebay supplier.

Essick air compressor wiring diagram


telepathy do not work that hot as in hollywood movies...

you need to provide a model or at least if this is three phase or single phase...

single phase is easy, you have cord with three wires, earth, active and neutral.

you need to open connection box on your compressor and you will find three wires there terminating in junction box, earth connect to earth (usually green or green with yellow stripes), then you have your neutral (usually brown or black) and active (usually blue or red), connect them, do not put cover on yet, plug cable into the power point and switch on/off power. check if motor is rotating in correct direction, if fuses are not blown... if motor is rotating in wrong direction - switch power wire with neutral wire, it just meant that you wired it in reverse...

do not need diagram for that...

do not forget to give some points...

3 Phase 7.5 HP air compressor overheat, runs on and off, we found it has no capacitor, what is the correct capacitor needed.


There could be several reasons why your unit is "overheating". Is the motor tripping the circuit breaker ? Is it the motor or the compressor that is overheating? I need more description of the problem. 3 phase motors do not have capacitors. Is the compressor turning the correct direction? Is the supply voltage correct? Is the power cable the correct size? Do you have the correct type and quantity of oil in the compressor?

Have a 3 phase compressor model vr5-8 want to know if it can be converted to single phase 230 volt and how


A 3phase motor cannot be rewired to run on single phase power. You need a phase converter. A 3-phase motor will only run on 3-phase power, and a phase converter will convert single phase power to 3 phase. Just google phase converter. There are two basic types, electronic and rotary. The rotary type are more powerful and efficient, but lot's more expensive than the electronic ones. Your only other option is to replace the motor with a single phase motor. Good luck.

I have a brand new IR compressor model 2475N7.5 with a 7.5 hp 460v 3 ph motor. is it possible to convert it to a single phase power supply? or should i just exchange it? ... I ordered it thru Northern Tool...


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.

I would like to connect a pressure switch to the motor starter


hi! there, single phase compressor motor need a starting capacitor base on the rated capacity in horse power,you can check this on the tag of the compressor motor how many horsepower was indicated,it should be for single phase motor starting capacitor has a capacity of micro farads.for a 1 horsepower = 15 to 18 micro farads stating capacitor if you have more than 1 horsepower you can basically proportion the value of capacitor you need or ask the dealer how much capacitor you need on your motor the connection of pressure switch with a four terminal should be connected both on common line L1 and running capacitor line L2 .if you open the cover of pressure switch there are 4 terminals,2 terminals are connected when normally close or no pressure they connected on series connection on the common line one terminal connected to common line of the compressor and the other terminal on L1 to the pushbutton switch to L1 supply line.the 2 other terminals also connected in series withe line capacitors L2 to yhr power supply line.hope this will help you a lot.just rate my fix thanks a lot.

I have this air conditioning unit where suddenly stops functioning and no power on the indicator. i have thecked the breaker and it is fine and ON with a three phase supply. I've checked the condenser at...


Hi, I will see if I can give you some idea of what may be happening. I work on these on a day to day basis. So, you have a split system with the condensing unit on the roof, or a package unit on the roof? Sounds to me it is the first one.So, you are telling me that the power supply at breaker below is OK, but you should have a power box at the condenser on the roof. When you reset power to the condenser, that's when you here this blast sound? To me from just hearing what you are saying , it would be the sound of the compressor trying to start up, and it has a internal problem making this noise. Tell me, when it makes this noise, does it trip the breaker again? If so, it is definatley the compressor. You can prove this if you are inclined to do this, is to find the 3 different wires going to compressor, and make sure power is off 1st. Disconnect them at the Contactor or remove the plastc cover from compressor and write down which wire goes to each terminal.Tape the ends so they dont touch metal. Turn the condenser back on and see if this blast is gone. If so, the compressor is dead and you will need a new one.You say you have 3 phase power? This is unusuall for a residential unit, 3 phase units are for comercial unit power. They dont use starting componants like Run or start caps because they have enough power to do the job.3 phase would have 3 hot legs of equal voltage unless it was the older 3 phase which will have a stinger leg with higher voltage then the 2 other legs.Maybe this is a commercial a/c. Also, the compressor is reversable on a 3 phase unit by moving 2 of the 3 wires on the load side of the box, like T-2 and T-3. If these are switched if the compressor is locked up, sometimes you can get lucky and break it loose.Please don't do this, I am just explaining to you a little about 3 phase. Try this so you can elimanate the compressor. The only other thing it could be, if this is a gas pack and you are starting the heat, you can be getting blow back premature combustion? But I don't think this is what you have. It has to be the compressor.So, lets prove it by taking it out of the circuit. all should hold and no noise.Still, a faulty compressor is not a good thing. Let me no. Best of Luck and safety first.
Sincerely,
Shastalaker7

Voltage problem


Most direct-drive electric compressors can run on a standard 110-volt circuit. When you get into the electric wheelbarrow compressors, you may have a choice for a dual-voltage option, which allows you to switch between 110-volt and 220-volt, depending on power supply that is available for the job. However, for jobs that require substantially more air, usually a 220-volt motor will be your only choice if a gas-powered compressor is not allowed as an option. When looking for a stationary shop compressor, you need to know what power supply you have at your disposal (208v, 230v, or 460v), and whether it is a single-phase or three-phase power. These units are usually hard-wired into the power supply and require a magnetic starter for thermal overload protection
