Abstract
A multiphase claw-pole type electric rotary machine has two or more phases-stator units. The stator units are arranged phase by phase in an axial direction of the electric rotary machine. Each phase stator unit comprises a pair of complementary-opposed claw pole core blocks and a ring-shaped stator coil sandwiched therebetween. The stator units have structures rotatably adjustable independent of each other in their phase positional relations while maintaining concentricity of them after assembly of the rotary machine before being secured.
