Abstract
An electric machine has a base body in which a stator of the electric machine is arranged. The electric machine has a rotor shaft which is mounted in the base body in bearings for rotation. The electric machine has a pick-up element connected in fixed rotative engagement with the base body and which taps a voltage present on the rotor shaft. The pick-up element is electrically connected to the base body via a capacitor and/or an ohmic resistor. A capacitance value of the capacitor is at least 1 nF. A resistance value of the ohmic resistor is between 10 mO and 10 O.
