A permanent magnetic rotor for an electric motor, preferably for an internal rotor motor, includes a laminated core consisting of several rotor sheets that are stacked in the axial direction. Permanent magnets are arranged in receiving pockets formed by recesses of the rotor sheets, the laminated core being composed of at least two differently shaped types of rotor sheets. Several rotor sheets of a first type of rotor sheet are provided as retaining sheets that respectively include a central yoke lamination section that is connected or can be connected to the rotor shaft and respectively one or more external pole shoe sections that are connected to the yoke lamination section by one or more connecting bars or bar sections, and several rotor sheets of a second type of rotor sheet are provided as intermediate sheets without connecting bars.

Permanent-magnetic rotor

The invention relates to a body of revolution, in particular for a centrifugal, which comprises a rotator, an electric motor with a stator and a rotor wherein said latter is fixed to the rotator for rotational movement therewith, a support to which the stator of the electric motor is attached and a bearing unit for rotational arrangement of the rotor around an axis of rotation which comprises at least one bearing adapted to coact with an electromagnetic stabilizer unit in such a way that disturbing forces and/or disturbing vibrations of the rotator are counteracted and/or compensated.
