The door drive includes a motor unit with a housing, in which a stator is stationarily received, and wherein a rotor is arranged so as to be rotationally-movable in the housing and includes an output shaft, wherein the output shaft can be brought into operative connection in a driving manner with the leaf element. The rotor includes a support body, on which receiving fields are formed, on which permanent magnets are adhered.
