Abstract
A stator for a rotating electrical machine includes a stator core, a stator winding disposed on or in the stator core, and an annular resinous seal which covers an axial end portion of a coil end of the stator winding. The resinous seal has an inner circumferential surface which is shaped to have a first inner diameter close to the stator core and a second inner diameter farther away from the stator core. The first inner diameter is selected to be smaller than the second inner diameter. This ensures the stability of electrical insulation of the stator winding.
