There is provided an electric motor/generator comprising a stator and a rotor. The stator has an outer perimeter. The rotor at least coaxially encloses the outer perimeter of the stator. The rotor is rotatable relative to the stator around a rotation axis. The rotor and the stator are separated by a flux bearing gap over which in working magnetic flux occurs. The rotor and the stator are separated by a protective gap. The protective gap is configured to close, during a deformation of the rotor, before the flux bearing gap closes, thereby avoiding closure of the flux bearing gap. The motor/generator is characterized in that the stator comprises a roller bearing and an axle. The roller bearing is coupled to the axle and rotatable around the axle. The axle is arranged off-center from the rotation axis. A distance between the roller bearing and the rotor defines the protective gap.
