Bertotti parameters

Bogdan Butnariu

Hello
I started studying my own engine, an IPM engine and it is not clear to me how to determine those Berotti parameters. (k1 k2 k3 and a1 a2 a3).
My motor must be at a frequency of 50 Hz, but from the results it shows me 100Hz, I took the Flu 270_35A material directly from the program without making any changes.
From what I read I have to declare those parameters specified above.
Eventually if someone has those parameters, can they help me with them?
Thanks and have a good day.

Hello Bogdan;

 

There is an excel too supplied with Flux to identify these parameters from measurements losses. Please have a look on the help to get more information on how to use this identification tool, as well as more information on iron losses computation.

 

The losses table can be found from suppliers website like cogent for instance, or you have to make a measurements.
