Abstract:
1. The multiphase claw-pole type electric rotary machine with two or more phases-stator units arranged phase by phase in an axial direction of the electric rotary machine, wherein each phase stator unit comprises a pair of complementary-opposed claw pole core blocks and a ring-shaped stator coil sandwiched therebetween, characterized in that the stator units comprise structures rotatably adjustable independent of each other in their phase positional relations while maintaining concentricity of said stator units after assembly of the rotary machine before said stator units being secured, wherein the two or more phase-stator units are joined to each other in the axial direction of the electric rotary machine through spigot and recess structures respectively to maintain concentricity of the stator units, and wherein a combination of the stator units are held at the both ends of the combination in the axial direction by end brackets through spigot and recess structures so that the positions of the stator cores can be rotatably adjustable phase by phase from the outside of the rotary machine after assembly of the rotary machine.
