Abstract An improved stator structure for a permanent magnet excited machine including a plurality of laminated main pole segments disposed about the armature of the machine, a solid yoke surrounding the pole segments and the armature, and a plurality of slabs of magnetic material disposed between the yoke and the pole segments. The improvement of the invention comprises a plurality of blocks of magnetic material disposed between adjacent main poles formed by the pole segments, and a plurality of laminated reversing poles, including windings disposed thereon, positioned between the main poles adjacent to and radially further inward than the blocks of magnetic material. The reversing poles and blocks are dimensioned so as to provide lateral air gaps adjacent each of the reversing poles between the winding thereon and the blocks of magnetic material disposed adjacent thereto.

Claim 1
Independent Claim
156 words
In a permanent magnet excited machine, a stator including a plurality of laminated main pole segments disposed about the armature of the machine, said pole segments forming a plurality of main poles about the armature, a solid yoke surrounding the pole segments and the armature, and a plurality of slabs of magnetic material disposed between the yoke and the pole segments, the improvement comprising: a plurality of blocks of magnetic material, disposed about said armature between adjacent ones of said main poles formed by said segments; and a plurality of laminated reversing poles, including windings disposed thereon disposed between said adjacent poles adjacent to and radially further inward than said blocks of magnetic material, said reversing poles and said blocks of magnetic material being dimensioned so as to provide lateral air gaps adjacent each of said reversing poles between said windings on each of said reversing poles and said blocks of magnetic material disposed adjacent thereto.
