Problems solved by technology

[0006] However, in this conventional technique, several steps of the forming process are required to form protrusions on the outer surface of the case
Therefore, the manufacturing process is complex
Also, since the protrusions are made of metal or resin, they may bend easily
Thus, the center guide supported by the protrusion may be unreliable, thus causing failure of the motor part

Abstract

Disclosed herein is a stepping motor, especially a stepping motor for a slim optical disk drive (ODD). A casing which protects and covers a stator of a motor part is divided into two casing parts, and a casing part adjacent to an end of a rotating shaft has at least two insert holes in an end plate thereof. Thus, a support member which supports a center guide is fastened to the casing in such a way that the support member is inserted into the insert holes. The casing part adjacent to the end of the rotating shaft is integrally formed with the support member by insert molding. Therefore, the stepping motor of the present invention can satisfy the trend of a reduction in size and thickness.

Description

technical field [0001] The present invention generally relates to a stepping motor for a low-profile optical disk drive (ODD), and more particularly, to a stepping motor having an improved housing structure in which the housing protects and covers the motor part of the stator, the housing is divided into two housing parts, and wherein the housing part adjacent to the end of the rotating shaft has at least two insertion holes in the end plate of the housing part so that the center guide is supported The supporting member of the (center guide) is fixed to the housing by being inserted into the insertion hole. The housing portion adjacent to the end portion of the rotary shaft is integrally formed with the support member by insert molding, thus meeting the trend of downsizing and thickness reduction. Background technique [0002] Generally, a stepping motor for an optical disk drive (ODD) includes a motor part and a lead screw. The motor part includes a rotor, a stator and a ...
