Abstract: An electric motor, in particular for a vacuum pump, with two magnetically coupled shafts. A correction force can be set on each shaft by means of adjusting magnet devices, whereby negative effects due to errors in the magnetic coupling can be compensated.

Abstract: A vacuum pump, particularly a Roots pump, claw pump, or screw pump. The vacuum pump has at least one rotor as a pumping device, which rotor is disposed on a shaft. The vacuum pump has at least one bearing and/or drive region for the shaft and at least one suction chamber. During a pumping process, a medium is conveyed from an inlet of the suction chamber to an outlet of the suction chamber, by means of rotation of the rotor. At least one gas conveying device is configured for conveying the medium away from the bearing and/or drive region in the direction toward the rotor and/or toward the outlet of the suction chamber.
