Kind Code:
A
Abstract:
PURPOSE:To reduce the pole core of an end by reducing the sectional area of the pole of the core arranged at the end of the core with a plurality of exciting coils as compared with that arranged at the inside. CONSTITUTION:A plurality of pole cores are composed in the size of the pole of inside by EXF when the size of the pole cores at both sides is CXD, and the dimensional relationship is set to CXD=(EXF)/2. A plurality of poles are alternately disposed at N-poles and S-poles. Thus, the sectional area of the pole cores disposed inside is larger by substantially twice of that disposed at the end. When the normal one is formed of the core 13, the pole core 1 disposed at the end can be reduced by half the size and weight.
