Abstract

PURPOSE: To enable a work of automatic assembly, by applying a method of unified forming for a front cover part and a magnet holding unit of the stator.
CONSTITUTION: One unit constitution is applied to a frount cover part 102A and a magnet holding unit 102B of the stator. A cylindrical yoke 112, made of soft magnetic material, being engaged with peripheral surfaces of said magnet holding unit, and hollow cylindrical magnet 103, being engaged with peripheral surfaces of said yoke 112 and magnet holding surfaces of the front cover, are provided. And the yoke and the magnet are successively cemented to be fixed to the front cover part and the magnet holding unit, further with one end face of a cylindrical external tube material 104, made of soft magnetic material, made fixing to a peripheral end of the front cover part. In this way, for quantity production of the coreless rotary machine, a product can be provided in a high precision additionally at low cost, becuase of adoption of the shape to each part with a highly mechanical precision material obtainable at low price.
