In electromagnetic or reluctance actuators, a thrust or reluctance force is generated due to a non-zero gradient of the relative magnetic permeability mu_r at surfaces between regions of different permeability (non-saturated ferromagnetic material: mu_r>>1, adjacent air: mu_r=1). In lumped magnetic network models, this force can be calculated as shortly outlined in Reluctance Forces of the User's Guide.
As an example of a reluctance actuator, a simple axisymmetric lifting magnet with planar end planes of armature and pole is shown. Often, a SimpleSolenoid model is sufficient for initial rough design of such an actuator's magnetic subsystem. Higher accuracy can be gained from an AdvancedSolenoid model where the coil-imposed magnetomotive force is split and the leakage flux between armature and yoke is accounted for more precisely.
The differences between these two models in static behaviour can be analysed and compared to results obtained with a more accurate finite element analysis (FEA) in ComparisonQuasiStationary. The resulting differences in dynamic behaviour can be analysed and compared to FEA results with simulation of a pull-in stroke in ComparisonPullInStroke.

Have a look at SolenoidActuator for general comments and at SimpleSolenoid and AdvancedSolenoid for a detailed description of both magnetic network models.
Similar to static force-stroke measurements on real actuators, the armatures of both actuator models are forced to move slowly here. Hence, the dynamics of the electrical subsystems due to coil inductance and armature motion can be neglected and the static force-stroke characteristics are obtained. To illustrate the accuracy to be expected from the lumped magnetic network models, results obtained with stationary FEA are included as reference (position-dependent force, armature flux and actuator inductance). Note that these reference values are valid for the default supply voltage v_step=12V DC only!
Set the tolerance to 1e-7 and simulate for 10 s. Plot in one common window the electromagnetic force of the two magnetic network models and the FEA reference vs. armature position x_set.y:
simpleSolenoid.armature.flange_a.f // electromagnetic force of simple magnetic network model advancedSolenoid.armature.flange_a.f // electromagnetic force of advaned magnetic network model comparisonWithFEA.y[1] // electromagnetic force obtained with FEA as reference
Electromagnetic or reluctance forces always act towards a decrease of air gap lengths. With the defined armature position coordinate x, the forces of the models are negative.
The magnetic flux through the armature and the actuator's static inductance both illustrate the differences between the two magnetic network models. Similar to the forces, compare these quantities in one common plot window for each variable (plot vs. armature position x_set.y):
simpleSolenoid.G_mFeArm.Phi // magnetic flux through armature of simple magnetic network model advancedSolenoid.G_mFeArm.Phi // magnetic flux through armature of advanced magnetic network model comparisonWithFEA.y[2] // magnetic flux obtained with FEA as reference simpleSolenoid.coil.L_stat // static inductance of simple magnetic network model advancedSolenoid.L_statTot // series connection of both partial coils of advanced network model comparisonWithFEA.y[3] // static inductance obtained with FEA as reference
As mentioned in the description of both magnetic network models, one can tell the higher armature flux and inductance of the advanced solenoid model at large air gaps compared to that of the simple model. The effect of this difference on dynamic model behaviour can be analysed in ComparisonPullInStroke.

Have a look at SolenoidActuator for general comments and at SimpleSolenoid and AdvancedSolenoid for a detailed description of both magnetic network models.
A voltage step is applied to both solenoid models at time t=0. The armatures of both models and therewith connected loads are pulled from their rest position at maximum air gap length to their minimum position that is due to a stopper. As a reference, simulation results obtained with a dynamic model based on stationary FEA look-up tables (not part of this library) are included. Note that these reference results are valid for the default supply voltage v_step=12V DC and the default load mass m_load=0.01kg only!
Set the tolerance to 1e-7 and simulate for 0.05 s. Plot actuator current, force and position of the two magnetic network models and the FEA-based reference vs. time (each quantity in one common plot window):
Plot window for current: simpleSolenoid.p.i // rapid current rise indicates low inductance of simple network model advancedSolenoid.p.i // current rise slower, better match with FEA reference comparisonWithFEA.y[1] // current obtained from dynamic model based on stationary FEA look-up tables Plot window for force: simpleSolenoid.armature.flange_a.f // reluctance force of simple actuator model advancedSolenoid.armature.flange_a.f // reluctance force of advanced actuator model comparisonWithFEA.y[2] // force obtained from dynamic model based on stationary FEA look-up tables Plot window for position: simpleSolenoid.x // armature position of simple actuator model advancedSolenoid.x // armature position of advanced actuator model comparisonWithFEA.y[3] // position obtained from dynamic model based on stationary FEA look-up tables
The characteristic current drop during pull-in is due to both armature motion and increasing inductance with decreasing air gap length. Bouncing occurs when armature and load of each model arrive at the stopper at minimum position. Although the pull-in times of the two magnetic network models are relatively close to the time obtained with the reference model, the accuracy of the advanced solenoid model is better, as one can tell from a comparison of the current rise at the beginning of the stroke.
