230v motors on 208v 3phase4/25
Curious if anyone here has run 230v 3ph euro motors on a 208v . I talked with SCM and Griggio and they say that just switch the lead on the transformer for the controls and I should be all set. Both said that the motors are designed for higher temps and long working hours. A one man shop should have no troubles.
Most services have variations in power to begin with. The service into my building is called 230 we transform some machinery to 460. When applying an actual meter to the main terminal you will find variations. Most of our power actually comes in around 215-225 volt or a low 230. There is no perfect voltage as my electrician explained it to me.
My power feeds have run on both high and low 230 systems in the 4 different shops they have been in for the last 20 years and still run strong. Most have thousands of hours on them. 3 steffs and a delta.
I would talk to a good commercial electrician in your area first and have him test to see what your actual voltage is.
It is true that running a motor on a low power draw will kill it prematurely but that is usually if its on to small a breaker or you can overload it on an oversized breaker.
yeah ,it's just you will be running a motor with a specified amperage at a higher amperage. The motor will run on what ever voltage you feed it as long as the mag starter will stick in and start the motor.
Seems like it's going to be o.k.. The griggio thicknesser has a 208v tap directly on the control transformer so it if the macghine was manufactured with a 208V tap you could assume that the motor would be fine run on 208V though rated 230v OR all the machines come with tramsformersd with both taps and the 208V motor was an option which this is not.... LOL
Most motors specify +\- 10%. That's 23 volts so you should be ok. Running at a lower voltage will make it run hot. After you run it for as long as you run it how hot is it?
Hello Bill thanks for the response.
I run all my machines on 208v. I have a separate boost transformer for my tablesaw. Everything else is on 208v.
Never had a problem, been there nearly a decade.
thanks Leo, that's the kind of thing I like to hear. What are you running on the 208?
I run standard shop equipment. 2 unisaws, 3 shapers, edge sander, dust collector, planer and jointer.
Rest of the stuff is 120v
When I setup shop I had the same worries as you. So I got the boost transformer for my most used pc of equipment, my tablesaw. I still use it because I have it.
We are also 208V and run LOTS of equipment on it. If I order new I get 208 and some things are still 230 and they say it is OK.
Thanks Guys, The planer started right up,, controls work great. It had a 208tap on the transformer.
The jointer...... is tripping a safety ... gonna have to call scm. Maybe I can just turn the breaker up a bit . If it's getting resistance from the voltage drop then I might be asking a few extra amps at start up. Odd thing is the breaker ( a 1A fused switch in the machine) pops right as you turn on the main not the cutter head.
Problems resolved. There was another mechanical fuse in the back that had tripped and couldn't see it had. Unsure why it had, maybe during the move????,,,
