Ansys Motor-CAD
Ansys Motor-CAD is a dedicated electric machine design tool for fast multiphysics simulation across the full torque-speed operating range. Motor-CAD enables design engineers to evaluate motor topologies and concepts across the full operating range, to produce designs that are optimized for performance, efficiency and size. Motor-CAD software’s four integrated modules—EMag, Therm, Lab, Mech—enable multiphysics calculations to be performed quickly and iteratively, so users can get from concept to final design in less time. 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 an electromechanical design. The release includes powerful new features for design optimization, multi-physics analysis and system modelling for electric motors. Fast multiphysics simulation across a full torque-speed operating range.

QCAD
QCAD is a free, open-source application for computer-aided drafting (CAD) in two dimensions (2D). With QCAD you can create technical drawings such as plans for buildings, interiors, mechanical parts or schematics and diagrams. QCAD works on Windows, macOS, and Linux. The source code of QCAD is released under the GPL version 3 (GPLv3), a popular Open Source license. QCAD was designed with modularity, extensibility and portability in mind. But what people notice most often about QCAD is its intuitive user interface. QCAD is an easy-to-use but powerful 2D CAD system for everyone. You don't need any CAD experience to get started with QCAD immediately. Construction and modification of points, lines, arcs, circles, ellipses, splines, polylines, texts, dimensions, hatches, fills, and raster images. Very complete and extremely powerful ECMAScript (JavaScript) scripting interface. Various powerful entity selection tools.
