The present invention provides to a rotor having a short circuit ring of an electrically conductive material. The short circuit ring has a curved outer surface whereby the eddy-current braking effect on the rotor caused by the stray field from the stator is reduced. The curved surface leads to an improved efficiency of an associated electrical motor. The invention further provides a motor with such a rotor and to the use of a rotor in an electrical motor.
