Electric Machines

Design, analyze and redesign are basic actions of a flowchart iterated as many times as necessary for the final product to conform to the requirements. In the important stage of analysis, the designer makes the difficult decision of whether or not to go ahead with the project, aware that inaccuracies lead to a false perception and postpone the need for redesign, naturally increasing costs involved. Obviously, the number of times and timing a product is redesigned is generally associated with the level of engineering.

The ideal scenario for any project is to have the possibility of designing, accurately analyzing and certifying compliance with the requirements even before carrying out prototypes and tests, possible with the use of appropriate engineering software that can accurately reproduce the physics involved.

SIEMENS offers software solutions to meet all project stages of an electrical machine. This range of tools make up an ecosystem called Simcenter and share a common point: integration.

In a high-performance environment, there is a need to carry out all stages of a project following a strict schedule, while the workflow must be as efficient as possible. With the use of Simcenter tools, the interchangeability of geometries and parameters is facilitated, as well as the sharing of results and generation of reports.

In the design of rotating electrical machines, the initial stages comprising the definition of topology, sizing, choice of materials, based on operating requirements, can be carried out by the Simcenter SPEED and Simcenter Motorsolve software , which have as their main characteristic the speed in delivering results of performance, due to the analytical or semi-analytical nature.

Considering a search for more accurate results in relation to prototypes, it is possible to export the models created in Simcenter SPEED/Simcenter Motorsolve to Simcenter MAGNET or create models of any electromagnetic device (motor, generator, transformer, linear actuator, etc.) and then, make simulations by Finite Element Method (2D and 3D FEM), in static or dynamic conditions and, finally, explore the different results in field charts, graphs and tables.

Also in Simcenter MAGNET, it is possible to export loss fields and force fields for thermal and vibroacoustic analysis, respectively. For these multiphysics couplings, Simcenter 3D has dedicated solvers with high capacity to evaluate the thermal and acoustic performance of electrical machines.

With the high level of integration and capabilities of Simcenter tools, it is possible to take the practice of electrical machine design to the highest levels, increase the competitiveness of products and meet strict regulatory and market requirements.

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.

Design electric motors with precision using    intuitive software . Simcenter Motorsolve is a complete design and analysis solution for permanent magnet, induction, synchronous, electronic, and brush-commutated machines. The software leverages finite element analysis with an intuitive interface for accurate simulations of electrical machines.

Perform low frequency electromagnetic field simulations with Simcenter MAGNET 2D/3D Finite Element software , a powerful electromagnetic field simulation solution for predicting the performance of motors, generators, sensors, transformers, actuators, solenoids or any other electromagnetic device.

SIMCENTER 3D: has the advantage of being a multi-CAD tool, allowing you to read with total precision software files from the main CAD's on the market from this opening and understand the context of product analysis, thus making it possible to load the model and the analysis.
