IEC / NEMA Shaft Heights

IEC / NEMA Shaft Heights

(OP)
Is their a motor frame dimensional charts for NEMA Motors above 355 frames, for a given HP / Speed relationship, where we could compare the difference between an IEC and NEMA motor

Refer to EASA MECHANICAL ENGINEERING HANDBOOK, there you find NEMA and IEC frame dimensions, etc.

RE: IEC / NEMA Shaft Heights

Ask your motor supplier for a poster/chart. Most motor vendors or repair shops can get these for you.

RE: IEC / NEMA Shaft Heights

magneticted, the link below has been quoted on this forum a while ago and gives a good comparison although it doesn't go beyond frame size 445T.

The site I frequently recommend is Brook Crompton (UK company), because their pdf catalogues are so good.  They have catalogues for IEC and NEMA, right up to the largest frame sizes, with performance and dimensional data.  You can find them on:

Their technical guides are good too.
