Abstract
An electric machine includes a stator, a rotor, an electrically insulated bearing unit for supporting the rotor, a transducer system, and at least one torque support for connecting the transducer system to the rotor and the stator. In order to prevent a potential equalization between the stator and the rotor as a result of currents induced in the rotor, the transducer system is electrically decoupled from the rotor and/or stator.
