    摘要： The present disclosure discloses an electric-machine housing structure, wherein the electric-machine housing structure includes an outer housing, an inner housing and a plurality of intermediate pieces provided between the outer housing and the inner housing; and the intermediate pieces are overall hollow arcuate structures or annular structures, upper surfaces and lower surfaces of the intermediate pieces are provided with a plurality of protrusions and/or grooves, the protrusions and/or grooves of the upper surfaces match with and are fixed to grooves and/or protrusions on an inner circumferential face of the outer housing, and the protrusions and/or grooves of the lower surfaces match with and are fixed to grooves and/or protrusions on an outer circumferential face of the inner housing.

    摘要： A slip ring includes an essentially cylindrical contact region defined by a radius and having a contact region which faces in a radially outwards direction. The contact region has a recess in a region of the contact surface, with the recess configured to have a projection extending on an inner side of the recess and/or being interrupted in a tangential direction. The contact region has an annular surface formed with an opening which communicates with the recess and extends towards an axial direction at an incline at an interval of 5 degrees to 45 degrees with respect to a normal of the annular surface. At least two insulating regions are arranged axially adjacent to the contact region and each being defined by a radius, with the radius of the contact region being larger than the radius of the insulating region.
