Multi phase motor with more than one FEM-Parameterized Rotary Actuator ?!?

FEM parametrized rotary actuator: This is a ONE phase input model ..
Is it possible to combine more than one to get a two-phase motor, a three-phase motor, a multi-phase motor, ecc... ?
Is there a little example of a model with a multi-phase motor made by more than one FEM-Parameterized Rotary Actuator blocks?

A two or three phase machine is better expressed using a machine model such as the ones found in the Simscape Electrical package. The parameterization that the model block is doing there with phi(i, theta) can be expressed for two and three phase machines as a positionally-varying inductance with saturation effects. The model is traditionally expressed in the rotating (qd) reference frame.
If it's a PM, this block should be adaptable: As a warning, obtaining the data from FEA for these models requires a sizeable amount of computation to sweep the parameter space.

however you parameterize this block, "FEM parametrized PMSM" you'll have a 3 phase port as input. I need a two-phase input. It should be nice and easy to adapt the source code of this block to a two-phase input, simply removing a Clarke transofrmation and keep the Park one for the dq reference working. Unfortunatly the sources ssc file are not avaible.

Ah, I didn't realize you had a 2-phase machine, or that the PMSM block wouldn't reconfigure itself to a 2-phase. You might be in a case where you need to build it yourself. Fortunately it sounds like you know the underlying theory.
