Abstract

The invention relates to a solid rotor of an electric machine and to a method in a rotor means. According to the invention a short circuit ring (18) of material having good electrical conductivity, such as copper, aluminium, bronze, brass, suitable alloy or similar, is attached to the end face (11) of the rotor means (10).
