Abstract
A highly precise coreless motor with improved precision of assembly in which weight is reduced by reducing the metal parts and reduction of assembly processes and time by means of a smaller number of parts brings down costs. There is a cylindrical external housing with a through hole in a central position in the closed end. A molded resin body is molded into place through the through hole of the external housing ; one end is a bearing that supports the rotating shaft, and it continues on the coaxial position of the rotating shaft to become a bearing housing that is fitted into place. The molded resin body is the base on which both the rotor and the stator are assembled.
