A permanent magnet rotor, intended for an electric motor, comprises a permanent magnet ring, which is held by a plastic support element and a sliding bearing. The permanent magnet ring comprises a compressed plastic-bonded rare earth magnet. The sliding bearing is made of a sintered material. The plastic support element can be produced in an injection mold. The permanent magnet ring includes a cylindrical receptacle for the sliding bearing and is made as one piece with a pinion. The plastic support element envelops the permanent magnet ring at least partially in the axial and radial direction and the permanent magnet ring can be injected simultaneously as an insert in the injection mold.
