Fast-analytical approach to motor design gets easier with software collaboration

Motor Design Limited Motor-CAD links with CD-adapco Star-CCM+ software to increase accuracy of a fast analytical approach to motor design while simplifying the modeling process of the CFD computation.


Motor Design Limited (MDL) has teamed up with CD-adapco to create a link between MDL’s Motor-CAD and CD-adapco’s world famous Star-CCM+ software. The collaboration aims to improve the accuracy of a fast analytical approach while simplifying the modeling process of computational fluid dynamics. This will result in a streamlined simulation process from Motor-CAD to Star-CCM+, the companies said.

Users will more easily integrate and combine Motor-CAD’s fast analytical airflow and heat transfer transient calculations with the impressive detail and accuracy of Star-CCM+ flow calculations. A simple interface (see photo) enables the user to transfer the Motor-CAD geometry into Star-CCM+ within seconds.

This will help to increase the accuracy of the thermal calculations in Motor-CAD and, at the same time, will increase and ease the use of Star-CCM+ for thermal designs of electrical machines.”

Dave Staton from MDL said, “CFD models have complex geometries. This link allows the customer to build their model quickly and accurately while capturing all the information they need. It allows for more flexibility in the design process because the designer can work on a machine simulation.”

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
