Abstract
The invention relates to a stator of an electric motor stator equipped with coils () and comprising an oil cooling system for the coils. The coils () are arranged leaving a gap () between them and defining inside and outside circumferences. The system comprises oil inlet and outlet manifolds pierced by orifices to send or recover oil to or from the coils. Each inlet orifice () is associated with a respective coil (), one of the manifolds surrounding the inside circumference while the other manifold surrounds the outside circumference, a flow of oil exiting each inlet orifice () circulating mostly in the gap () between its associated coil () and at least one of the two adjacent coils () and then exiting via an outlet orifice.
