Magnetic & Motor Design Features Added to Siemens Simcenter Software 

Some new capabilities for designing magnetic systems in electric motors are part of an update by Siemens EDA to its Simcenter Magnet software. The new updates to the Simcenter electromagnetics (EMAG) solutions accelerate a designer’s ability to model complex problems and further integrate the Simcenter EMAG solutions. 

The new improvements to Simcenter Speed, Simcenter Motorsolve and Simcenter Magnet help designers model the complexity, go faster, explore possibilities and stay integrated, according to Jonathan Melvin, technical marketing manager. An improved DXF overlay in Simcenter SPEED allows the user to automatically see updates to parameters and create a facsimile of their motor from a template. The new Step-Skew option for rotor or stator topologies in Simcenter Motorsolve more accurately models the possible manufacturing processes for skew. This new skew method simulates a more accurate cogging torque. Creating a new motor is 37% faster due to response time updates, says Melvin.

Eddy currents can induce a breaking effect that can be both desired and undesired. Therefore, it can be essential to model the impact of eddy currents in Simcenter MAGNET. Accounting for motion-induced eddy currents in actuators was not available in Simcenter MAGNET’s previous ROM technology but is now in this latest release.

It is now possible to complete an EMAG data exchange for computational fluid dynamic thermal studies with the improved data file exchange. Temperature-dependent data exchange for materials is now available in Simcenter SPEED GoFER’s for Simcenter MAGNET and Simcenter STAR-CCM+. This is helpful because, for the best FEA results, appropriate temperatures and temperature-dependent material properties for each component of the motor are essential.

Similarly, as depicted in image at top, additional coil-side phase winding descriptions have been added to Simcenter SPEED, allowing designers to define more detail in their simulation and provide crucial parameters for a simulation. For more info, see
