Description of the Related Art In recent years, in order to facilitate the processing of a lead wire, a stator of a motor has a housing in which a lead wire lead-out portion is formed, and the attachment of the lead wire to the stator winding is abolished. There is a tendency to go. However, when the lead wire is abolished, a part of the stator core is cut off to fix the terminal case, which may be disadvantageous to temperature rise, noise, and the like. Less than,
An example of a conventional motor stator will be described with reference to FIGS. 4 and 5. FIGS. 4 and 5 are a plan view and a bottom view, respectively, of a conventional stator core having a terminal case attached to the stator core after and before the stator winding is inserted. Reference numeral 1 denotes a stator core having a cutout 9 on the side surface of the outer peripheral portion, and reference numeral 3 denotes a terminal case integrally formed of a thermoplastic or thermosetting resin having electrical insulation. This terminal cable
The terminal 3 has a built-in terminal 5 to connect the winding end of the stator winding 2 to a lead wire, and inserts and attaches it into a cutout 9 provided at the center of the stator core. To this end, a projection 12 is provided on the terminal case, and a notch 9 is formed in the stator core 1 so that the projection can be inserted, and the projection is inserted into the notch and fixed. .

As shown in FIG. 5, a notch must be formed near the minimum width of the inner and outer diameters of the stator core, and the width of the inner and outer diameters of the stator core is further reduced. Then, when the stator winding is inserted and energized, vibration is apt to occur, noise is increased, and magnetic saturation is apt to occur, resulting in an increase in temperature. In addition, since the fitting portion between the notch and the projection is small, the stability is poor and there is a problem that the terminal case may fall off. The present invention has been made in view of the above problems, and provides an electric motor stator that can fix a terminal case without using a minimum width of an inner diameter and an outer diameter of a stator core.
