The invention relates to an electric machine with a stator (), with a rotor and with multiple machine coils (). The electrical machine comprises a cooling device, which is suitable for cooling a superconducting material to at least below a transition temperature. Windings () of at least two machine coils () consist of the superconducting material and are assigned to different winding groups. The windings () are operatively connected with the cooling device, in order to cool the windings () to below the transition temperature. The electrical machine comprises an open-loop or closed-loop controlled power supply device, electrically conductively connected with the windings (), for the supply of electrical power and controlling of the machine coils (). At least two winding groups are each electrically-conductively connected with a separate, open-loop or closed-loop controlled power output stage () of the power supply device. The separate, open-loop or closed-loop controlled power output stages () are arranged within the thermal insulation area () of the electric machine delimited by the thermal insulator.
