Simulation and Modeling in Electrical Engineering

The SimulationX domain Electrical Engineering permits the modeling and simulation of electrical and magnetic phenomena using network models. In addition, detailed models for motors and stepping motors as well as the respective controllers link this domain to the libraries of the Power Transmission domain. The parameterization is application-oriented and follows established engineering principles.

 

Thus, the complex behavior as it appears in controlled electromechanical drives is easily modeled and simulated.

SimulationX Libraries in Electrical Engineering

 

Electronics

Using the Electronics library tasks in electrical engineering and electronics can be solved efficiently. The library contains strongly idealized elements as well as realistically modeled components. Therefore, the elements are applicable for various application fields (mechatronics, power electronics, switchgear construction). Special sensor and actuator elements seamlessly integrate the electronics models into other engineering fields.

 

Magnetics

The Magnetics library allows modeling of electro-magnetic drives in terms of magnetic equivalent circuits.  For this purpose, the library provides lumped network elements which can be used to describe approximatively the distribution of the magnetic flux. The structure of the magnetic circuit is strongly oriented towards the real system, which results in efficient and intuitive modeling. 

 

Electric Motors

Using the electric motor models, modeling and simulation tasks in electro-mechanic drive technology are solved efficiently. The close-to-reality models use an application-oriented parameterization concept and thus are easy to handle. In combination with the libraries in the Power Transmission domain complex controlled drives can be simulated, considering the mechanical components as well as the controls too. The motor models are applicable to various engineering fields (machinery drives, hybrid automotive powertrains, rail vehicle drives, etc.)

 

Converters

The Converter library provides models, which allow a controlled operation of the motors from the Electric Motors library. The library provides field-oriented controllers for synchronous and asynchronous motors, PWM controllers and 3-phase converters.

 

Stepping Motors

The library permits the modeling of stepping motor drives, which operate in full or half step mode, as well as Microstepping. The stepping motors are operated via controllers, which are also part of the library. The controllers operate as voltage or current controllers and additionally support pulse-width-modulated (PWM) and two-point operation. The stepping motor models seamlessly combine with models from the domains Mechanics and Controls.
