Novel Co-based soft magnetic materials are a potential substitute for electrical steels in high speed motors.These materials have: low losses, high permeabilities, and good mechanical strength.We present a finite element analysis of Parallel Path Magnetic Technology (PPMT) rotating motors constructed with both silicon steel and Co-based nanocomposite.The later achieved a 70 % size reduction and an 83 % reduction on NdFeB magnet volume with respect to a similar Si-steel design.
