Design Principles

"Virtual prototyping through simulation can de-risk and accelerate the design of complex electromechanical systems."

This modeling capability allows designers and engineers to virtually test and optimize motor designs under realistic, often imperfect, power supply conditions early in the design process. It reduces the need for costly and time-consuming physical prototypes for every design iteration, accelerating innovation and improving product reliability.

What This Means for Your Design

Using computer models (like FEM) can help predict how electric motors will work, even if the power supply isn't perfect. This saves time and money by reducing the need for lots of physical tests.
