ABSTRACT:
According to the invention, an electrical machine stator comprises a housing, a core, a winding mounted on the core, the upper and lower bars of said winding being connected in pairs in the end winding portion so as to form heads, a supporting member installed in said housing, which supporting member is constructed, in accordance with the invention, as a ring having a cylindrical projection whose height corresponds to the length of the end winding up to the heads, the stator being further provided with brackets whose supporting surfaces are arranged at an angle to the internal surface of the cylindrical projection, there being arranged wedges in the space between the internal surface of the cylindrical projection and the supporting surfaces of the brackets, which wedges are held in place by elastic members. The proposed stator is intended for high-power electrical machines, where it is necessary to ensure reliable fastening of the end winding in different operating conditions.
