Can a machine using 220v 60Hz 3 phase be plug into a 230v 50hz plug

dear

is it three phase 230 V 50hz supply in Singapure.

That item can be looked up.

you can run this motor without any problem

same thing which done by me at our plant .

it is running without any problme

only the motor will run 10 to 15 % slow speed with its rated speed

speed = 120f/p

your voltage rating almost same.

and your phase is also same.

only the frequency is 50HZ

but if you rung 50hz motor with 60hz frequency then problem occure.

your motor life is decrease but in your case

its running wihtout any problem

you can do this..

SB,

Another GA for you from me. One additional warning I wish to add though for the original poster.

Since the motor in question requires 3 phase, the expected work from this motor likely will not be small. So the 17% reduction in shaft power, speed, cooling etc. could easily be the difference between operation and smoke. If this is only a temporary rig that you (OP) can nurse along to prevent trouble, then I would say an attempt would be worthwhile. Just CYA by having everybody that uses this machine realize that this is a temporary kludge rig. If this is a permanent installation, then get the correct motor. Remember, you are not just providing torque for a machine with your motor choice. You are also establishing your reputation.

Dear One,

You can use 230v ac,50hz in place of 220v,60hz, it will run bit lower and bir warmer, nothing will happed and you may not notice the difference,

Thanks

The motors ratings are not for normal operation and the device that uses the motor should have a voltage controller/regulator to take care of some of the problem of a potentially altered voltage. So.. the motor itself will be fine (albiet slightly slower), but you could possibly damage controls or any controller/regulator that might be wired and grounded differently in conjunction with the motor itself.

What is the device? That makes a huge difference...

Go for it.. If it fails, you know it was wrong. If it smokes from the speed control device, it was wired differently.. If it explodes and starts a fire.. get everyone out of the house/office/theatre... If it goes thermonuclear and you have a chance to pray.. Do it.

Guest,

A lot of people are saying "no problem". I disagree. SB has stated it well--see the other threads in the last few months on this topic. Depending on the application you may never have anything go wrong. But motors designed for use with both 50Hz and 60Hz always indicate their power output is lower on the 50Hz mains.

A worst case experience could be a motor failure leading to injury to people or damage to the plant. Investigation would show that it was an improper installation and the insurance company can then come back to you and charge you with negligence. Or someone dies and you get charged with their death. You then lose everything. "No problem"? Not hardly.

I have a similar problem but the inverse. I have a cylindrical grinder thats from England and is set up for 50hz. I don't have 3 phase so I am planning on using an inverter and am hoping I can get one that will convert 220/60hz 1 phase to the 50hz 3 phase that I need.

I haven't started investigating inverters but I assume that if its a rotary inverter you should be able to go from nearly any input to nearly any output as long as the total input/output are similar and your not trying to put a 10 hp motor on a 5 hp inverter.

Yes you can. Perfectly safe and well within tolerances which should be posted on the device somewhere.

i believe we should know more about that machine , coz so far everyone is talking about the motor problem, but only one mentioned that it depends on which kind of control on the machine u have also we need to know if you have valves or contactor coils that operate on the same line , also you have to be sure about that information of the 230V/50Hz as it can be 230V single phase & 380V three phase and that is very important .

we will wait to hear from you

It should be ok as far as supply and plug are concerned. You need tio check with download equipments for their suitability.

Motor will run, but with hot motor body and could lead to trip out. (check with infrared thermometer and observed)

Recommendation:

* to chage the motor or rewound based on site requirements

* if you cant afford to spend more bucks, you may opt to install fan/blower in order to reduce motor body heat but need continous observation and insure the sorrounding ambient teperature is cold.

FYI
