PROBLEM TO BE SOLVED: To provide a magnetic function apparatus which has its structure made simpler by further decreasing the number of components.SOLUTION: A magnetic function apparatus includes a magnetic pole group G1, a magnetic material group G2, and an armature group G3, and members P1, P2, and P3 which support the respective groups while the respective groups are arranged one over another in order in an axial direction or radial direction. The magnetic pole group G1 comprises N1 magnetic poles M1 arrayed to have rotational symmetry which is an even multiple about an axis Q. The magnetic material group G2 comprises N2 magnetic materials M2 arrayed to have rotational symmetry about the axis Q. The armature group G3 comprises N3 (N3=|N1±N2|) winding type armatures M3 arrayed to have rotational symmetry which is an integral multiple of 3 about the axis Q. |
