FreeCAD
FreeCAD is an open-source parametric 3D modeling tool that can be used to design real-life objects. Parametric modeling allows for easy modification of your design by going back to your model history and changing its parameters. FreeCAD allows you sketch constrained geometry 2D shapes and then use them to build other objects. It has many components that allow you to adjust dimensions and extract design details from 3D models. This allows you to create high-quality production-ready drawings. FreeCAD is a multiplatform (Windows, Mac, and Linux) software that can be customized and extended. It can read and write to many open file formats, including STEP, IGES and STL. FreeCAD can be used for a variety of purposes, including product design, mechanical engineering, and architecture. FreeCAD is for everyone, whether you're a programmer, a professional CAD user, or a hobbyist.

Ansys Motor-CAD
Ansys MotorCAD is a dedicated tool for electric machine design. It allows you to quickly simulate multiphysics across the entire torque-speed operating range. Motor-CAD allows engineers to evaluate motor topologies across the entire operating range. This allows them to create designs that are optimized for size, efficiency, and performance. Motor-CAD software's four modules, Emag, Therm Lab, Mech, allow multiphysics calculations to be performed quickly, iteratively, and users can move from concept to final design in a shorter time. Motor-CAD users can explore more motor topologies and fully evaluate the impact of advanced loss effects during the initial stages of an electrical mechanical design with Motor-CAD's streamlined data input process. This release features powerful new features for design optimization and multi-physics analysis, as well as system modeling for electric motors. Multiphysics simulations are fast across the entire torque-speed range.
