Claims

[Claims for Utility Model Registration] (1) A plurality of stator sets each consisting of a winding wound around a coil bobbin and a plurality of magnetic poles arranged facing each other so as to sandwich the windings are connected in the axial direction. In a small electric motor having a stator disposed in the same direction and a rotor rotatably supported on the inner periphery of the stator, a notch is formed in the disc-shaped yoke of the magnetic poles arranged in series. At the same time, a protrusion corresponding to the notch of the magnetic pole and extending in the axial direction and having a thickness substantially corresponding to the thickness of the magnetic pole is formed on one of the flanges of the coil bobbin, and the protrusion of each of the plurality of coil bobbins is formed. A small electric motor characterized in that parts are arranged and fixed so that parts are adjacent to each other and face each other. (2) A claim for utility model registration characterized in that the protrusion of the coil bobbin is formed with a small hole through which the lead wire is inserted, a narrow groove through which the winding end extends, and a recess for accommodating the connection part. A small electric motor as described in scope 1. (3) The protrusion of the coil bobbin is characterized by forming a concave groove having a narrow opening into which the lead wire is inserted, a narrow groove over which the winding end extends, and a concave portion for accommodating the connection portion. A small electric motor according to claim 1 of the utility model registration claim. (4) On the surface of the protrusion, in order to fix two adjacent coil bobbins facing each other, a small protrusion having a size approximately the same as the width of the narrow groove is formed in the opposing portion of the narrow groove. A small electric motor according to claims 1, 2, and 3 of the utility model registration claim, characterized in that:
