Three Phase Motor Data 1

Post a photograph of the nameplate. That should detail things like frame size etc. Sounds like a fairly standard motor from the little information you've posted. I've never heard of the manufacturer.

Here's the motor nameplate details.

It's a TECO part number - here's the AEEB catalogue.
Might give you a starting point - maybe worth a call to TECO in your area to decipher the full part number?

Dear Sir,

Where are the motor located? in USA or Europe?

If you are in USA I will take account is an IEC motor with all sizes in milímeters, not so many american manufacturers have in stock this kind of IEC motors but Siemens could be the appropied contact, this group manufacture both NEMA and IEC motors.

Another point is the wrong voltage data in the name plate information for 60 Hz.

Good Day!

@ petronila
The motors were located here in asia.it were actually a factory choice by Grunfos coupled to one of their pumps.
@ scottyUK
that's our problem sir, deciphering the code for us to identify the proper frame size, etc.

regards,

If it is an IEC motor - which it certainly appears to be - then you should be able to measure the major parameters like shaft height and mounting centres which should get you the frame size and any modifer for short / medium / long frame. Bearing type should let you see if you have a standard motor or a variant designed to accept axial loads. My guess is that it could be a factory 'special' built for Grundfos - maybe an extended shaft or similar - but that can be accomodated by any decent manufacturer.

Hello Hooverdale

Like Scotty saids is necessary to take some readings in the motor.
The attachment contains the Foot mounted IEC electric motor´s sizes, the most importants are H: this size will give you the Frame and B wil gives you the size(Small, Medium and Large Size), so for correct frame specifications you need to know the letter, Example: H = 180 mm will belongs for a motor frame 180) but you have three chances for B reading: 203 mm (S )and produce a motor 180 S , 241 mm for 180 M and 279 mm for frame 180 L. Also check the shaft diameter size and ask to the dealer if is the same for the spare part motor.

Thats right. We did actually measured the motor parameters. And thanks to Carlos' frame sizes table we identified its frame size. That table was very helpul.
Cheers!
