What's New

Ansys Motor-CAD is now offering electric machine engineers the ability to innovate even more on their motor designs with the new adaptive template capability and achieve higher accuracy with the high fidelity efficiency mapping.

New Cooling Methods

Explore new cooling approaches and model your motor design more accurately by introducing three new cooling options commonly used in the automotive sector. You can now explore new cooling possibilities that were not previously available.

Upgraded Workflows

Increase flexibility to innovate quickly and easily with additional enhancements to the adaptive template geometry capability. The embedded Python commands allow users to customize templates and add custom geometry parameters. Users can also build up their IP library.

Enhanced Electromagnetics

Model eccentricity in induction motor designs. You can now calculate the static and dynamic eccentricity and study the effect on noise, vibration, and harshness. The hybrid FEA method now calculates both proximity and skin effect losses. This is also available for Litz wire.


Integrated Multiphysics Analysis Software for Electric Motor Design

With decreasing development cycles, motor designers need to make design decisions quickly, and with certainty that they will not face problems down the line. Fast calculations and streamlined data input processes leave time for Motor-CAD users to explore more motor topologies and fully assess the impact of advanced loss effects in the initial stages of a design.

Motor-CAD software’s intuitive, template-based setup and embedded multiphysics expertise simplifies the design process and reduces reliance on multiple teams for specific electromagnetic, thermal or mechanical experience — so motor designers can keep more control over their designs. 


Key Features

Motor-CAD delivers high-fidelity, 2D/3D analysis capability enabling users to analyze end-effects, demagnetization, core loss, hysteresis and other advanced electromagnetic phenomena, calculate the thermal envelope for operation and design complete motor cooling systems

  • Design for Field Weakening
  • Temperature Dependent Continuous-Torque and Peak-Torque Simulation
  • Manufacturing Effects and Housing Interfaces.
  • Ratio-Based Optimization
  • Magnetic Force Analysis
  • Rotor Stress Analysis

Ansys Motor-CAD connects to Ansys Maxwell for advanced 2D and 3D electromagnetics analysis. For electric machine noise and vibration and (psycho-acoustic) sound prediction, Ansys Motor-CAD integrates with Mechanical and VRXPERIENCE. It also connects with Ansys CFD solvers and leverages air, water and oil based cooling techniques for cooling system design and analysis, as well as provides feedback into the Motor-CAD’s thermal model.

Comprehensive and powerful geometry templates enable the complete electric machine design space to be explored. Templates cover a huge range of electric machine technologies, topologies and cooling systems. Ratio based parameterization options are a new addition which provide unprecedented capabilities for parametric design optimization.

Coupled multi-physics analysis from the start of the design process and in-built control algorithms enables virtual testing considering temperature effects over transient drive cycles or at steady state.

Design of modern electric machines requires performance analysis over the full torque/speed operating range. Motor-CAD enables designers to easily and quickly analyze the performance of their designs over the operating envelope, including field weakening behavior.

Rapidly evaluate designs against the complete multi-physics performance requirements such as peak and continuous torque/speed characteristics.

Any electric machine simulation requires understanding of the manufacturing effects and the impact of variation in the manufacturing process on performance. Motor-CAD has built in knowledge to guide engineers in configuring the manufacturing effects appropriately and enables straightforward sensitivity analysis to understand the impact of manufacturing variation on performance.

Motor-CAD is the ideal tool to use for optimization of electric machine designs. Powerful ratio-based optimization enables the design space to be explored easily while the coupled multi-physics analysis enables evaluation of each candidate design against the complete performance specification.

Automatically extract and visualize magnetic forces as a function of time and space, over the full operating range. Enabling NVH analysis of a design.

Rapid, automatic FEA based rotor stress analysis enables engineers to easily optimize rotor designs and trade-off between electromagnetic performance and mechanical constraints.

Multiphysics Optimization of Electric Motor NVH Behavior

Noise, vibration, and harshness (NVH) are essential aspects that must be considered when designing and optimizing a motor. Using Ansys Motor-CAD with Ansys optiSLang, we show how to optimize the motor’s noise alongside the motor’s electromagnetic, thermal, and mechanical requirements. As the design matures, structural information from Ansys Mechanical can improve the rapid analytical structural model, increasing the fidelity of the solution while maintaining the speedy solution times that allow fast design optimization.
