Converter (electric to mechanic)

Converter (electric to mechanic)

Hi,

I attempt to construct a new Model in Modelica. It want convert a electric energy to a mechanical force to move a mass or drag a spring. I have considerate the  follow equations:

Input of the model (left side)
  v = p.v - n.v;
  0 = p.i + n.i;
  i = p.i;

convert the performance to the force ( P = f *v)
  v * i = f * der(s);

   
  flange_b.f = -f;
  s = flange_b.s;
   
Can everyone help me to develope a workable model?
Thank you in advance!

Andy

Re: Converter (electric to mechanic)

Hello Andy,

I like that you want to model the conversion by equal power, but you are missing an equation. I think you still need to specify that there is a relation between force and current (if you go for a motor type of actuator).  There are these kind of models already available. Might Modelica.Electrical.Analog.EMF or Modelica.Electrical.Analog.Gyrator not be ok for you?

Good luck
Bas
