Abstract :
A buried magnet rotor structure, which is supported only by permanent magnets, is proposed for medium speed permanent magnet machines. Different solutions with pole numbers six to fourteen are studied with electromagnetic and structural finite element simulations. An optimal solution with optimal pole number is discussed.
