Abstract: A magnetic coupling assembly includes a rotatable male coupling member, a rotatable female coupling member, a static separation member, a first channel, a second channel, a third channel, and a magnetic coupling section of the static separation member, wherein the magnetic coupling section is a section of the static separation member. The rotatable female coupling member and the rotatable male coupling member are rotatably coupled by magnets through the magnetic coupling section. The first channel, the second channel, and the third channel contain fluid forced to flow through the first, second, and third channels for cooling and rotodynamic stabilization.

Abstract: The invention provides a magnetic coupling assembly (1), comprising: a rotatable male coupling member (2) comprising magnets (3); a rotatable female coupling member (4) comprising magnets (5); a static separation member (6) arranged between the male and female coupling members, a first channel (7) in a gap between the male coupling member and the separation member, a second channel (8) in a gap between the female coupling member and the separation member, an axial internal channel (9) in the male coupling member, a magnetic coupling section (10) of the static separation member, wherein said magnetic coupling section is the section of the static separation member between the magnets of the male coupling member and the magnets of the female coupling member, wherein the female and male coupling members are rotatable coupled by the magnets through the magnetic coupling section of the static separation member.
