The forces on the rotor all tend to center the rotor within the rotor path.

Said rotor (1) comprises at least one flow channel (7) for the transport of liquids and/or gases into and/or out of the sample container (11), wherein means for centered mounting of the rotor (1) are provided on the rotor (1).

The external rotor (4) is rotationally mounted on the internal rotor (3).

At the rotor there are firmly fitted lateral plates (14) that rotate jointly with the rotor.

An apparatus includes a rotor and a magnet disposed on the rotor.

The stator (10) and rotor (50) are also mechanically coupled through a plurality of magnets (61) positioned on either the stator (10) or rotor (50).

The point (21) is traversed along the rotor (4) while keeping the point (21) at the same position on the rotor profile.

The loop is positioned on the rotor.

The rotor (10) is equipped with blades (11) that rotate with the rotor (10) and are fixed to the latter (10).

The eccentric rotor group (200) comprises a cylindrical rotor (4) provided on the shaft (2) and rotatable therewith, and a collar (3) rotatablely provided on the cylindrical rotor (4).

The magnetism of the magnetic pole located on the internal rotor (1) is opposite to the magnetism of the magnetic pole located on the external rotor (3).

The tool includes a rotor mount face disposed on the rotor being tested.

The rotator is a rotor of a motor, and an output rotation shaft on the rotor is canceled.

Corresponding impeller and turbocharger are also provided.

The rotator is coupled to the crankshaft, rotates about the axis of the crankshaft, and has an internal gear that meshes with the external gear on the rotor.
