335 HP Motor for Auto Shredder

335 HP Motor for Auto Shredder

335 HP Motor for Auto Shredder

(OP)
I have a Schorch Motor (60 Hz, 250 kW, 480V, 360 A, 335 HP).  I am trying to find a direct substitute for this motor.  Can I get some suggestions on manufacturers or a dealer in/around the Texas area?

I'm currently trying to repair this one but will need a spare in case something happens to it.  The Schorch was manufactured in 2005 and but we didn't actually start the auto shredder until 2006.

Thank you!

RE: 335 HP Motor for Auto Shredder

You didn't mention the base speed or the frame number or t0he NEMA design but with that additional information, I would think any of the major motor manufacturers would quote.  The exception would be if it was over 8 pole (900rpm at 60hz).  That would include Baldor/Reliance, TECO/Westinghouse, GE, Weg, and maybe even Marathon.

RE: 335 HP Motor for Auto Shredder

OK, this is a metric IEC motor in 315L frame built to NEMA 60hz 460V six pole Design A specs.

The 315 in the frame number is 315mm shaft elevation and the L is for long length along the shaft.  There are also S and M for short and medium.

Seeing this new information, I am sure that ABB Motors Group in New Berlin WI will bid on this motor.  Phone is 800-752-0696.

RE: 335 HP Motor for Auto Shredder

I'm not hugely familiar with Schorch products but if the serial number follows convention, the -Z on the end of the type number means it is a variant or modified type but doesn't actually denote what the changes are: could be a non-standard shaft length or flange arrangement, or any of a multitude of other things. Sometimes the easiest thing to do is to ring the manufacturer with the serial no. and ask what the variations are the standard design. The fact it is an IEC motor built to NEMA standards might be enough to have generated the -Z. Just something to be aware of when assessing bids.

Siemens Europe would probably build a motor to this spec for you - maybe an option to explore through Siemens US.

Thank you both!

Also, the rpm's are 1188 for this motor....just found that out.

RE: 335 HP Motor for Auto Shredder

Yes, Siemens Energy and Automation (Siemens US) can provide IEC frame motors. You need to contact this division. Schorch has a US marketing arm through a rep in Texas however.

RE: 335 HP Motor for Auto Shredder

Why would only an IEC frame motor work here ? After all, the motor is designed for 60 Hz, 480 V american environment. Any of the american manufacturers, as stated by DickDV in his first post, should be able to supply the spare.

RE: 335 HP Motor for Auto Shredder

(OP)
In case this matters, it was installed in a German made "Metso-Lindemann" Shredder.

RE: 335 HP Motor for Auto Shredder

No, it doesn't. The load doesn't care what the motor is as long as it does the job. Moreover though the frame is IEC, the motor design as per NEMA standard. Any american motor made to that spec will do the job, even if the shredder is german :).

RE: 335 HP Motor for Auto Shredder

Schorch doesn't make NEMA frame motors that I know of. Most likely it's their standard design with a nameplate converted to HP instead of kW, hence the "335HP" rating. So it's doubtful that a motor designed to US standards will physically mount and couple without modification. I did a project requiring replacing a Schorch motor on an N2 gas compressor here in the US, it was a very difficult motor spec to work with, yet the OEM in Finland used them all the time everywhere else in the world and had no problem finding replacements.

RE: 335 HP Motor for Auto Shredder

The motor might be built to NEMA electrical specs but the IEC mechanical specs make the conversion to NEMA a matter of some study.  Shaft elevation, shaft length and diameter, foot position and setback are all different and would have to be accommodated somehow.  And, when you get all done, the NEMA motor has to FIT into the hole the IEC motor came out of.

Get the general drift here???

RE: 335 HP Motor for Auto Shredder

Dick  - yes.

So let's study those mechanical mounting specs before deciding to discard the motors made in your own backyard.

RE: 335 HP Motor for Auto Shredder

I have a feeling this motor might be made by Siemens anyway, for Schorch. I might be wrong.
The part number ends with a "-Z" and this is very Siemens-like indicating there is 'something special' about it. Usually tracing the serial number will indicate to the factory (Schorch) that the "z= xxxx" (something).
As DickDV and edison123 point out, check out the complete motor before assuming it is a straight replacement.
Thee is a Schorch outlet in Texas on the link jraef provides.
