Electric motor validation and verification

Electromagnetic Analysis

The electromagnetic design and optimization of the motor, provided by Ansys Maxwell and Ansys optiSLang, determines the radial, tangential, and axial forces associated with the machine's performance.


The acoustic representations of radiating vibrational noise are imported into Ansys Sound, enabling users to hear the electric motor at varying rpms.


Simulation results from Ansys Maxwell and Ansys Mechanical provide key inputs to realize the goal of measuring auditory perception and assessing a vehicle’s NVH performance. The structural simulation incorporates these forces in the presence of the motor housing.

Ansys Sound

Hearing the motor enables engineers to isolate and identify sub-components of the acoustic profile and investigate the influence on human perception.

Multiphysics Simulation Accelerates the Motor Design Process 

Ansys offers a full system integration based on the ability to extract information from the design stages into analysis, design for validation and into the final verification stage. This enables full system simulation in one workflow.

Electric motor design using system-level structural simulation


With template-based setups, initial electric machine designs are developed quickly. System-level structural simulations enable more investigations and thus more robust innovation. The automated analysis process, with its built-in electromagnetic, thermal and mechanical solvers, offers valuable multiphysics insights into an electric motor design.

Electric motor thermal analysis


In electromagnetic simulation, the resulting advanced 2D and 3D calculations  incorporate  additional  effects that impact the motor’s performance. Thermal analysis predicts the temperature rise within the motor configuration based on given operating conditions. 

Electric motor validation and verification

Ansys system integration allows for virtual validation of component design and verification through embedded systems.
