  • Mounting of permanent magnets on a rotor of an electric machine
    Patent number: 10211693
    Abstract: A rotor for an electric machine has a surface with projections. Each projection protrudes from the rotor in an essentially axial direction and is configured to define a groove between the projection and the surface. The groove of one projection of two adjacent projections and the groove of the other one projection of the two adjacent projections is open towards a region between the adjacent two projections. A cover engages in the grooves of the adjacent two projections, and a sealing compound is applied in the form of a fillet seam between the cover and the adjacent two projections. Received in an intermediate space between the cover and the surface is a permanent magnet, and a pouring compound is received in a remaining hollow space defined between the permanent magnet and the cover and/or the permanent magnet and the surface.
