synchronous motor model in SKM - how to create one?
synchronous motor model in SKM - how to create one?
(OP)
Hi,
I will have to produce a TMS report in SKM. In order to do it I have to gather all needed information. The Models in the library seems to be appropriate for asynchronous motors. Or, at least, to synchronous motors only for transient periods (when the equivalent circuit of a synchronous is similar to a asynchronous equivalent circuit). How can I model the steady-state and starting equivalent circuits?
Thanks for help!

TMS is a Transient Motor Starting analysis. A synchronous motor starts as an induction motor anyway, so for modeling it's starting effect on the syupply, I just treated it as such.

I guess the last option might avoid any mistake due to transformation or report to the stator.

Good luck.

Quite a difference: the one using the graphical model starts faster (2.5sec) than the equivalent circuit (5.5sec)!!!
And I had all info from motor supplier, just ready to enter in SKM models library.
I attach the PDFs of the resulted curves. Maybe there is an explanation you might find. I give also an XLS file with all data to build the models.
Thanks,
