Model and Simulate Complex Electric Motors

A simulation platform solution for electric machines encompasses design and analysis of multiphysics and system modeling approaches to address electromagnetic, thermal, acoustic and drive performance. Ansys Maxwell allows engineers to import an entire 3D motor geometry from any CAD tool. Maxwell automatically creates the 3D circumferential slice-based model, applying nonplanar cuts as boundary conditions and corresponding regular and symmetric mesh (clone mesh) on all parts of the geometry.

This approach allows Maxwell to solve only a fraction of the original 3D space and display field results back onto the initial 3D geometry. Moreover, solving electromagnetics on newly reduced space designs, Maxwell allows coupling with thermal solvers and a structural harmonic solver where the full 3D geometry is required, imposed by the nature of different physics. The ultimate secret to this method and the benefit to the customer is the application of non-planar cutting boundaries to assign proper electromagnetic symmetry in the much-reduced design space. This gives you the most accurate and symmetric mesh of even the skew rotors and stators without increasing the computation cost.

Without a doubt, the new methodology is becoming the new best practice for motor design simulation of complex 3D geometries. This is a powerful solution that allows entry- or senior-level engineers to work on a project quickly and solve models with record speed and accuracy.

Performance Analysis of Electric Motors for EV Powertrains

Developing a battery EV powertrain is a complex systems problem. Ansys Maxwell enable us to design and development of electric motors in an EV powertrain, capturing how the different design choices — such as motor topology, winding type and cooling system — can be compared and evaluated considering their overall system impact. Ansys simulations can help engineers determine whether an interior permanent magnet (IPM), an induction magnet (IM) or a wound field synchronous magnet (WFSM) is the best motor design for an EV. Ansys also considers the trade-off between hairpin and stranded winding technologies and can compare three different methods for motor cooling.
