Is this single or 3 phase?

[bigcreek]

By looking at this plate can anybody tell if it is 3 phase or single phase? It doesn't come right out and say it that I can see but didn't know if there is some kind of code word for it or something?

 

[bigcreek]

I see a 1 in the "S" column but don't know what S stands for.

How many leads in the motor junction box?

 

[bigcreek]

Ill have to check it out. Its at an auction and was just looking at it online. Its a metal cutting saw.

 

[humber2]

3 phase and 2 speed.

Hope you get the switch and wiring intact with it.

3 phase .....

How do you figure?
It's 8.3A @ 220V and 1.5kW. 3-phase would be far less.

 

[Dr.Joe]

Its 3phase. The triangle/double star behind the 220V means that this is a Dahlandermotor... I just have the german wikipedia-page for it, sry.

[fnieto]

Yup, the 220 Delta/ YY on the data plate indicate such.
Is that a Scotchman cold saw?

It is as dr. Joe indicates. Get the cut sheet from emod if you still have time before auction. Send them pic of nameplate. Go to emod-motoren.de and fill in the contact info.

Wow... learned something today. Thanks guys!

As said Dalander motor is wired for 3 phase with delta winding for slow speed and double wye for high speed. The connection change would be done by an external specific-purpose switch as mentioned.

Yes it is a Scotchman cold saw. Thanks for the info guys much appreciated

I thought it looked familiar.

The "S" might be referring to the duty rating of the motor. Another Euro motor I have has a "Duty" field on the nameplate and it is marked "S1". This is in addition to also having a "SF" field" of 1.15.

Interesting. I couldnt see those symbols on the first few looks at it.

Why no HP rating?

Another issue, since this is a european motor, is the voltage and frequency! Nominal US voltage is 240v 60hz not 220v 60hz...

 

[Dr.Joe]

The HP rating is not commonly used in europe for motors.
It's the same with tools: the US seems to indicate the current draw even for marketing purposes. In Germany we use the power rating

 

[mm08822]

1 kw ~ 4/3 hp

Definitely 3 Ph. Pretty much a Euro spec motor other than the frequency...
