STATOR OF ELECTRIC ROTARY MACHINE AND FABRICATION METHOD THEREFOR

摘要

One embodiment provides a stator of an electric rotary machine, including: a stator core having plural slots; a segmented coil of plural phases; and plural base plates laminated at each end of the stator core in an axial direction. While the stator core and plural coil bars of the segmented coil form a stator core assembly, and the plural base plates and plural end coil connections of the segmented coil form plural base plate assemblies. The stator is configured by the stator core assembly and the plural base plate assemblies laminated at each end of the stator core assembly.

1. A stator of an electric rotary machine, including:
a stator core having plural slots; a segmented coil of plural phases; and plural base plates laminated at each end of the stator core in an axial direction, wherein the segmented coil includes
plural coil bars which are individually inserted in the plural slots in the stator core and which extend substantially straight andplural end coil connections which are disposed on each of the base plates to form spanning portions to connect the coil bars of the same phase together, wherein the stator core and the plural coil bars form a stator core assembly, wherein the plural base plates and the plural end coil connections form plural base plate assemblies, and wherein the stator is configured by the stator core assembly and the plural base plate assemblies laminated at each end of the stator core assembly.
