Stator for e.g. revolving electric machine, in electric car, has cylinder head formed by parts, where difference between diameters of parts defines edge extending between peripheries of parts against which coolant circuit is positioned

摘要

The stator (1) has a body (2) including a cylinder head (3) having an annular form and teeth (5) delimiting notches extending from an internal periphery from the cylinder head towards the interior of the stator. The cylinder head of the stator is formed by an annular part (19) and another annular part (20) that are coaxial to each other. Difference between external diameters of the annular parts defines an edge (14) extending between external peripheries of the annular parts against which a coolant circuit (17) is positioned.
