Milwaukee, WI (PRWEB) March 27, 2012 announces a pre-conference workshop at Electrical Manufacturing & Coil Winding Expo 2012: Reducing NdFeB magnet cost for Vehicle Traction Motor Generators. This two day event will take place in Milwaukee, WI on May 7-8, 2012. There is a special discount on the registration fees for EMCWA members.

JH-workshops offer a forum to discuss and understand how to overcome the challenges faced by machine designers today. This workshop focuses on professional development, combining theory with an interactive design session, which gives attendees the opportunity to both learn new and refine their existing techniques under the guidance of Jim Hendershot.

Recent escalating cost and supply limitations of NdFeB permanent magnets have had a significant impacted on the business models relating to the manufacturing costs of motors and generators used in hybrid and electrical vehicles.

During the first day of the workshop, four design strategies will be presented in order to mitigate the impact of these rising costs:

????Use traction motors and generators that require no magnets
????PM rotor designs with reduced magnet volumes
????Designs that use low cost ceramic, Strontium Ferrite magnets
????Designs optimization of IPM utilizing combinations of ceramic and neo

The second day will consist of a team oriented interactive design session using a provided software tool.
