Abstract

Funded by the Grainger Foundation and NASA, efforts are being made to help advance state-of-the-art induction motor (IM) and permanent magnet synchronous motor (PMSM) technology by reducing machine size and weight. High frequency, high pole count designs are being explored to reduce/eliminate the use of ferromagnetic iron in the magnetic circuit, and addressing corresponding electromagnetic, thermal, and mechanical implications. Detailed analysis is being performed using analytical and numerical models which capture the multi-physics trades associated with this approach. The opportunity for increased power density using the high frequency, high pole design has been demonstrated for PMSMs, and effects of similar approach to IMs are currently being explored.
