Simulation and Modeling in Electrical Engineering

The SimulationX domain Electrical Engineering permits modeling and simulating electrical and magnetic phenomena using network models. Additionally, detailed models for motors, stepping motors and converters link this domain to the libraries of the Power Transmission, Control Engineering, Fluid Power and Mechanics domains for comprehensive simulations of coherent systems. The parameterization is application-oriented and follows established engineering principles. An interface to the FEA software JMAG allows realistic models of electromechanical components – with parameters obtained from CAD data – to be used in SimulationX’ system simulation. Thus, the complex behavior as it appears in controlled electromechanical drives can be easily modeled and simulated.

 

 

SimulationX Libraries in Electrical Engineering

 

Electronics 

By the help of 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 can be used 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 for modeling electro-magnetic drives as magnetic equivalent circuits.  For this purpose, the library provides lumped network elements which can be used to describe  the approximate 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 

Electric motor models help to solve modeling and simulation tasks in electro-mechanic drive technology efficiently. The true-to-life models use an application-oriented parameterization concept and are thus easy to handle. In combination with the libraries in the Power Transmission domain, complex controlled drives can be simulated including the mechanical components as well as the controls. The motor models can be used in 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 also support pulse-width-modulated (PWM) and two-point operations. The stepping motor models seamlessly combine with models from the domains Mechanics and Controls.

 

Electromagnetic Model Elements with Interface to JMAG-RT

Use the Interface to JMAG-RT to integrate highly detailed, fully parameterized models of electromechanical components into SimulationX. JMAG-RT-models of motors, generators, reactors, solenoids and actuators (including nonlinear electromechanical behavior, such as torque ripple, cogging torque, magnetic saturation and iron losses) can be seamlessly connected to model elements from SimulationX’ libraries for realistic and significant simulations of complex mechatronic systems.
