A method for operating an electric machine of a compressor and/or of a turbine, which includes a rotor situated on a shaft mounted rotatably in a housing and a stator fixed to the housing, the stator including an, in particular, multiphase drive winding, and an activation of the drive winding being suspended at least intermittently in an idling mode. It is provided that the shaft and/or the rotor is/are monitored for a rotary movement, and that, when a standstill or an impending standstill of the shaft and/or of the rotor is detected, the drive winding is activated in such a way that the rotor, at least briefly, is caused to carry out a movement and/or is centered with respect to the stator by magnetic force.
