Claims

[Scope of Claim for Utility Model Registration] (1) A coil bobbin consisting of a body and a flange integrally formed at both ends thereof, an annular winding wound around the coil bobbin, and a structure surrounding the winding. In a small electric motor that uses a flexible flat cable (hereinafter referred to as FFC) as a means for leading the winding to the outside, the end of the FFC connected to the winding is A stator for a small electric motor, characterized in that the stator is formed in an arc shape corresponding to the flange of the coil bobbin. (2) Two sets of coil bobbins and windings wound on the bobbins are provided, and in order to derive the ends of each winding,
Utility model registration claim 1, characterized in that the end of the FC on the side connected to the winding is divided into two, and each of the two divided ends forms an arc shape so as to face each other.
Stator for the small electric motor described in Section 1. (3) The FF is placed on the flange surface of the coil bobbin.
A stator for a small electric motor according to claim 1, characterized in that a recess is formed to accommodate an arcuate portion of the C-connection side end.
