Model Ferrite Core Using Magnetic Core Block
Adjust the Jiles-Atherton parameters to obtain a good fit for the B-H curve of a magnetic core. The Magnetic Core block uses the Jiles-Atherton model to define the relationship between the magnetic flux density, B, and the total field strength, H. You can parametrize the block by specifying the Jiles-Atherton parameters directly. Alternatively, you can parameterize the block using saturated B-H curve data or by specifying magnetic characteristics. If you do not specify the Jiles-Atherton parameters directly, the block estimates the Jiles-Atherton parameters based on the assumption that you have a saturated iron core. This estimate is not always accurate for other types of core, such as ferrites with small values of coercivity and remanence. Always check that the B-H curve the block uses matches your input data.

Solenoid Parameterized with FEM Data
A limited travel solenoid with return spring. When unpowered, the spring holds the plunger at a distance of 0.1mm from the fully energized position. At 0.1 seconds, the solenoid is powered on and the displacement goes to zero. At 0.06s a force higher than the holding force is applied, and the plunger moves to its maximum travel of 0.2mm. The solenoid force and back emf characteristics are defined by the FEM-Parameterized Linear Actuator block. This block takes data in the format typically provided by a finite element magnetic field modeling tool. There are two parameterization options, one which works directly with flux data, and one which uses partial derivatives of flux with respect to current and displacement. The latter option is usually the better choice, it giving more accurate results for a given density of current and position data points. However, it requires more data pre-processing.
Stepper Motor Pull-in Characteristics

Torque Motor Parameterization
How manufacturer data for torque as a function of current and angle can be used to model a torque motor.

Data in this range is used to parameterize the simplified model of the torque motor. Using MATLAB® to process the data points extracted from the datasheet, we can convert manufacturer data into motor parameters that are often obtained from finite element software.
