Generate a current with solenoid blocks

Hello everyone,

I have a group of students trying to make a simscape model of a vertical wave energy converter. The basic principle is that the waves move a magnet vertically through a fixed coil, hence producing an electrical current.

We tried using the magnetic solenoid model (matlab command: ssc_solenoid_magnetic) and reversing it. We put a translationnal source generating a force on the mechanical side and we put sensors on the electrical side. I monitored each segment of the model with scopes and the problem is the Reluctance Force Actuator which seem to just not work in this direction.

I also tried using the solenoid block (simscape > electrical > electromechanical > mechatronic actuators) in the same fashion and the result is the same.

Is there a way to make this work with simscape or do we have to make a causal model ?

Thank you for your help.

Hi Alexandre,

Kindly attach your Simscape model to help resolve the issue effectively.

Hi Alexandre,

For a simple model you could use the Translational Electromechanical Converter. You can drive this from the mechanical side and set the constant of proportionality to get the appropriate voltage/current on the electrical side.
