Sheet metal holder for retaining permanent magnets

A rotor for an electric motor, comprising:

• a rotor basic body having a longitudinal axis, axial ends, and a plurality of radial resting surfaces;
• a plurality of permanent magnet bodies, each arranged on a respective one of the radial resting surfaces, each of the plurality of permanent magnet bodies pointing radially outwards, each of the plurality of permanent magnet bodies having a radial outer circumferential surface radially outward of the radial resting surfaces;
• a sheet-metal holder associated with each respective permanent magnet body arranged on a portion of the radial outer circumferential surface of each of the plurality of permanent magnet bodies;
• wherein the sheet-metal holder is configured to fix the respective permanent magnet body radially with respect to the rotor basic body, and
• wherein the respective sheet-metal holder covers the respective permanent magnet body on its side facing away from the respective resting surface in a circumferential direction of the rotor in a central region of the respective permanent magnet body from a first longitudinal end of the respective permanent magnet body to a second longitudinal end of the respective permanent magnet body parallel to the longitudinal axis and leaves respective peripheral regions uncovered,
• wherein the sheet metal holder has a plurality of legs that extend radially inwards towards the longitudinal axis at each respective longitudinal end of the plurality of permanent magnet bodies that corresponds with the axial ends of the rotor basic body and each leg terminates at a radially inner end, the radially inner ends of the respective legs being joined by a ring arranged at the axial ends of the rotor body,
• wherein an entire radial outer circumferential surface of each of the plurality of permanent magnet bodies is planar.
