Altair FluxMotor - Thermal Design, Test, and NVH Evaluation

Integrate models for mechanical, electrical, and controller subsystems to simulate your mechatronic product holistically as a system-of-systems. Exchange models and/or co-simulate with other CAE tools either from Altair (such as Altair MotionSolve® and Altair Flux®) or from 3rd parties through the Functional Mockup Interface (FMI) open standard.

Altair Flux offers faster and more accurate 3D magnetostatics analysis thanks to the implementation of new integral method. This is extremely interesting for applications with a lot of flux leakage in air, such as sensors modelling. No air mesh is required, dramatically reducing the computation time versus classical finite element method and offering much higher accuracy.

The presentation outlines a solution strategy for how a digital twin of a milling machine is solving mechatronic challenges. To improve cycle times, accuracy, and addressing vibration problems a holistic system simulation serves as the basis for optimization. The efficient modeling of the real system behavior with flexibilities, contacts, gaps, friction, nonlinearities in the drives (incl. saturation effects of motors), power electronics in combination with the control system is the basis for efficient controller design and optimization of the control parameters. The dynamic interaction of multiple system components combining 3D finite elements analysis multi-body dynamics and control system helps avoiding Tracking-, drag-, positioning errors rebound, and accumulation effects.  

Altair software is used across industries to solve a broad range of electromagnetic problems from static to low and high frequencies. Whether your application requires multiple frequency and time-domain techniques with true hybridization to enable the efficient exploration of a broad spectrum of electromagnetic performance, other the simulation of magneto static, steady-state and transient conditions, we have the tools you need.

Designing an efficient motor has always been a complicated set of tasks. Altair's multidisciplinary optimization platform is a solution that allows considering multiphysics parameters and conflicting constraints.

The design of a high-performance e-Motor is a complex undertaking. Engineers have conflicting constraints to consider including efficiency, temperature, weight, size and cost. To explore more ideas, better understand their designs and improve performance, Altair HyperWorks™ has a workflow to guide motor designers through an efficient process of Simulation-Driven Design. This analysis and optimization solution supports multi-disciplinary teamwork and reduces design times.

Taking magnet demagnetization phenomena into account during solving process offers more accuracy on typical quantities such as motor torque or electromotive force and new analysis like the evolution of the remanent flux density.

Presentation by Andy Dyer, Senior Tech Specialist at Altair.

In this presentation, we'll take a look at a few examples of e-Mobility systems models built with Altair Activate and Compose and integrated with other tools like Flux, for electromagnetic simulation for electrical machines (motor/generators), for the purpose of simulating power electronics and motor thermal behavior. We'll also take a look at integrating system model via third-party software like CarSim via the use of the Functional Mock-up Interface, which opens the door to a multitude of tools for further system integration, including packages like MapleSim and DSHplus in the Altair Partner Alliance.
