Hello PB75,
while you could translate between rotational mechanical motion and translational motion, and then fit the motor parameters to give you equivalent performance of the actual linear motor, I would recommend against it. You won't be able to paramaterize the motor correctly, and instead have to fit the parameters to lab data, and at that point, you might as well use lookup tables and controlled sources. You would also be unable to capture accurate dynamics if you ever needed high fidelity simulations. For something like a PhD, I would highly recommend going through the effort of implementing/deriving the equations for a linear motor/generator.
Both Simscape Electrical and Specialized Power Systems allow for the customization of blocks.
If you use simscape, you would get started here:
If you use specialized power systems, you would use this feature:
Personally, I would use Simscape for this type of model, as there isn't a good equivalent to start from in the Specialized Power Systems for this and you can start from scrach with Simscape.
Again, if you don't want to do this, I would just use a lookup table to approximate a simple linear machine.
Regards,
Joel
