Transient FEM Simulation of a Solenoid Actuator with MAXWELL

Click For Summary
SUMMARY

The forum discussion centers on a 3D transient electromagnetic simulation of a solenoid actuator using MAXWELL software. The user successfully imported geometry from CAD files and set up the motion, meshing options, winding, and coilterminal with an external circuit. However, the simulation results indicate that while a force acts on the plunger, its speed and position remain unchanged, suggesting an issue with the movement vector configuration. The user seeks assistance in refining the mesh and resolving the movement problem.

PREREQUISITES
  • Familiarity with MAXWELL software for electromagnetic simulations
  • Understanding of 3D CAD modeling techniques
  • Knowledge of transient electromagnetic analysis principles
  • Experience with meshing techniques in simulation software
NEXT STEPS

Hey Guys!

Hi Guys!

Well I am new here and I have to confess that I somehow got stuck in a 3D transient electromagnetic simulation of a solenoid actuator and… I’m a mechanical engineer^^ So I would appreciate some help of you guys!

1. I imported the geometry from CAD-files. But I remodeled the coil and the plunger with a sweep of the section around the z-axies.

2. I added a vacuum Band around the plunger

3. I setup the motion with:

4. I added some meshing options

5. I added a winding and a coilterminal with an external circuit

6. I setup the Solution:

7. I solved itSo the solving went smooth but the mesh is not very refined jet. I get a Force acting on the plunger but the speed and the position of the plunger they don’t change...

It somehow seems to be a problem with the movement. The moving vector has to be positive apparently. I will keep you posted
 

Thread 'uA709 op amp compensation'

Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
