SPEED

Simcenter SPEED

Design and analyze motors and generators analytically in Simcenter SPEED, which provides access to theoretical and physical models of most major classes of electrical machines (for example, electrically excited synchronous and permanent magnet machines, induction, reluctance, DC with brushes, switched with field and axial flux winding), along with their drives.
In addition, Simcenter SPEED writes a predefined set of specific parameters and maps that can be imported into Simcenter Amesim, supporting system-level simulation of the electronic machine integrated into its environment.

Electric machine rapid design  software

Simcenter SPEED features

Industry's most used rotary machine design software

Link with Multiphysics software

Automated Design Space Exploration and Optimization

Simcenter SPEED software supports engineers in virtually validating design choices through detailed analytical simulation, fast and intelligent use of 2D finite element magnetostatic analysis. It includes all the theoretical and physical models needed for rapid electrical machine design with a flexible approach and an interface with links to even more accurate and detailed analyzes and simulations such as 2D and 3D Multiphysics Finite Element/Finite Volume (FE/FV) magnetostatic or magnetotransient, thermal, mechanical or vibroacoustic.

​

  • Electric machine model: set up an electric machine model quickly;

  • Multiphysics software link : model export to finite element software ;

  • Design Exploration: Evaluate the influence of parameters or optimize machine performance for one or more objectives;

  • System-Level Simulation: Export model data for a system-level simulation in Simcenter Amesim.

  • ​

Simcenter SPEED supports the most common machine types including motor, generator and also inverters.

The user can benefit from predefined templates for the following machines:

  • Synchronous machines (PC-BDC)

  • Induction machines (PC-IMD)

  • Switched reluctance machines (PC-SRD)

  • Brushed PM-DC machines (PC-DCM)

  • Wound Field Switched Machines (PC-WFC)

  • Axial flow machines (PC-AXM)

  • ​

To improve simulation accuracy, Simcenter SPEED provides links to several general purpose electromagnetic finite element solvers such as Simcenter STAR-CCM+, Simcenter MAGNET or to Simcenter SPEED's dedicated tool, SPEED FEA Solver. They make it possible to model and study the electrical machine more accurately and under specific conditions, with saturation and the occurrence of faults.

In general, users can connect Simcenter SPEED with other tools needed for complete electrical machine solution using various scripts or programming languages. More specifically, automation makes use of scripting capabilities , driving Simcenter SPEED alone, or in conjunction with other programs such as STAR-CCM+. This automated workflow follows the scripting approach and uses STAR-CCM+ and its multiphysics solvers for electromagnetic, thermal (full 3D conjugated heat transfer) and mechanical stress analysis, along with Java scripts to provide and provide additional information.

Vibroacoustics can also be studied by combining FE models of the stator and frame subsystem with a BE model of the surrounding free space to assess the sound quality of the electrical machine. The objective is to eliminate noise through simulation in Simcenter 3D Acoustics.

What is the expected end result of this Model-Based Systems Engineering approach? Answer: a support for making the best design choice , and by “best” I mean the optimized viable choice, again through an efficient and continuous workflow.

As mentioned, Simcenter SPEED delivers results almost instantly thanks to its analytical approach, which makes it very suitable for Design Space Exploration programs, supporting clients with “What if” studies and optimization runs.

HEEDS is a powerful software package in the Simcenter portfolio that automates this process of exploring the design space, and Simcenter SPEED provides an integrated graphical user interface for accessing HEEDS.
