Motor CAD Software

About Motor-CAD


Motor-CAD is the world-leading dedicated electric motor design software package for the multiphysics simulation of electrical machines across the full torque-speed range. Developed in 1998, Motor-CAD is used by major motor manufacturers and universities worldwide.

Motor-CAD enables design engineers to evaluate motor topologies and concepts across the full operating range, to produce designs that are optimised for performance, efficiency and size. Motor-CAD software’s four integrated modules—EMag, Therm, Lab and Mech—enable multiphysics calculations to be performed quickly and iteratively, so users can get from concept to final design in less time.

Why Motor-CAD?


Explore more motor topologies and assess the impact of loss effects at any early stage in the design process, when the cost of change is low

Ever-reducing development cycles are forcing motor designers to make design decisions quickly and with certainty they will not face problems down the line. With Motor-CAD, multiphysics calculations can be carried out in just seconds: creating space in the design process for motor designers to explore more motor topologies and fully assess the impact of advanced loss effects at an early stage, when design choices are still open and the cost of change is low.

Streamlined and simplified design process

Comprehensive multiphysics simulation in the initial stages of the design process prevents costly mistakes, which is why many major OEMs and Tier 1s use Motor-CAD even when they have existing software solutions in place. Motor-CAD software’s intuitive, template-based setup and embedded electromagnetic, thermal and mechanical expertise simplifies the design process and removes the need for extensive multiphysics experience.
