Intuitive, template-based set up
Comprehensive and powerful geometry templates cover a huge range of electric machine technologies, topologies and cooling systems. Ratio-based parameterization options provide unprecedented capabilities for parametric design optimization.
Design across the full operating range
Quickly analyze the performance of designs over the operating envelope, including field weakening behavior.
Built-in electromagnetic, thermal and mechanical solvers
Coupled multi-physics analysis from the start of the design process and built-in control algorithms enable virtual testing considering temperature effects over transient drive cycles or at steady state.
Thermal sizing of the machines
Ability to predict the thermal behavior of electric machines through a built-in 3D thermal network.
Electromagnetic and vibro-acoustic design of electric motors
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.
Acoustic
The acoustic representations of radiating vibrational noise are imported into Ansys Sound, enabling users to hear the electric motor at varying rpms.
Vibration
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.
