Parameterize Blocks from Simulation Results
Use Simscape™ Electrical™ blocks and simulation data to:
Create low-fidelity models of motors, semiconductors, and DC-DC converters, using functions that generate reduced-order models (ROMs) of high-fidelity Simscape subsystems.
Represent motor designs that were developed in finite element method (FEM) software by importing the flux linkage, torque, and loss characteristics into Simscape.

Switched Reluctance Motor Parameterized with FEM Data
Build a model of a Switched Reluctance Motor (SRM). A custom Simscape™ composite component is used to construct the three stator pole pairs using the Simscape Electrical™ FEM-Parameterized Rotary Actuator as a base component. The states of the input pins (reverse, on/off) control the torque applied to the motor shaft.
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.
Parameterize a Permanent Magnet Synchronous Motor
Estimate the back EMF and torque constants of a blackbox permanent magnet synchronous motor (PMSM) with an unknown flux linkage. You can use either the back EMF or torque constant to describe the flux linkage and parameterize a Simscape™ Electrical™ PMSM block. This parameterization allows you to accurately replicate the blackbox motor's behavior in simulation.
