Jim Hendershot is a prolific world traveler, having visited 34 countries while teaching electric machine design and consulting in many of those countries since 1966. His latest textbook on electric machine design, co-authored with Prof. TJE Miller has been transuated into the Japanese language.
He has served as a consultant for Infolytica Corp. in Montreal since 2005 for their electric machine Design software products. In the fall of 2017, Infolytica was aquired bythe Mentor Graphics div. of SIEMENS and Jim Henderhot continues this annual consulting relationship with Mentor-Siemens.
