IEC motor standard frame size
IEC motor standard frame size
(OP)
Hi,
I have the question about the IEC standard kW rating since I got the proposed motor rating 380kw instead of 400 kW and 420kW instead of 450kW.
As I check with the European well-known motor manufacturers e.g. ABB, Siemens, their standard motor kW rating seems to be standardized and are the same such as ...,315, 355, 400, 450 kW,...etc.
Is this manufacturer's standard rating are the same as IEC standard rating or frame size or not ? I also have seen IEC60034-12 shows the rated kW differently from these European manufacturers.
I am not sure what standard for which the kW rating according to these European manufacturers are based on ? can anyone tell me about this ?
Thank you,

However, sometimes manufacturers will give you their ratings as mechanical power at the shaft, which is the standard motor kW multiplied by the motor efficiency. They usually provide this in hp, but this may be what's happening in your case.
