How find Lm(and other ) parametr for ACIM?How correct Lm from saturation iron ACIM?

Dmitry,
Not sure exactly what you are asking. You want someone to tell you how to ID the motor parameters of an induction motor without using InstaSPIN-FOC? I don't think you will have much success with that question on this forum. Anyone who has their own motor parameterization / characterization solution is unlikely to share the details. We have spend considerable effort in creating the motor ID solution as part of InstaSPIN, and this is the only format in which we are offering to support.

Hi Chris.

I want to try t model acim.

I know ud and uq voltage.

Set load torque zero.

Start motor to nominal speed.And calculate Id current

and Ud voltage.I know frequense and I think calculate

complex Zlm=Ud/Id.After thry find Lm.

Dmitry.

the best I can do is offer the documentation we provide in InstaSPIN-FOC on Motor ID. See SPRUHJ1
