Nanocomposite soft magnetic materials are presented as a potential substitute for electrical steels in high speed motors. The low losses, high permeabilities, and good mechanical strength of these  materials enable application in high rotational speed induction machines. We present a finite element  analysis of Parallel Path Magnetic Technology rotating motors constructed with both silicon steel and Nanocomposites.  The latter achieved a 70% size reduction and an 83% reduction on NdFeB magnet volume with respect to a similar Si-steel design.  We will also present current ideas on axial and induction motors and magnetocaloric cooling.
