  • Magnetic gear with a magnetic flux conductor arrangement
    Patent number: 10432078
    Abstract: The present invention relates to a magnetic gear comprising a first magnetic rotor with a first shaft; and a second magnetic rotor with a second shaft; a support structure, with a first end shield and a second end shield connected by a stat or support element. A first bearing attached to the first end shield supports the first shaft and a second bearing supports the second shaft. The first and second magnetic rotors are displaced in axial direction from each other in an axial gap; and the first shaft and shaft are approximately aligned in opposite axial directions; and a plurality of magnetic flux conductors encircles the first and second magnetic rotors, thereby conducting magnetic flux from the first magnetic rotor to the second magnetic rotor. The magnetic gear comprises a dividing wall arranged in the axial gap between the first magnetic rotor and the magnetic second rotor, to separate a first chamber from a second chamber.
