A drive axle for an electric vehicle, having a transmission and an electric motor formed as a separately excited synchronous machine having a rotor, a stator, an excitation unit, and a hollow rotor shaft with an outer diameter. The electric motor is coupled to the transmission via the hollow rotor shaft. The excitation unit is arranged inside of the rotor shaft and comprises an exciting part, which is formed so as to be static and not rotating with the rotor shaft, and an excited part which is fixedly connected to the rotor shaft and rotates along with it. In order to facilitate installation of the excitation unit inside the rotor shaft, the rotor shaft is formed of two parts with a first rotor shaft part and a second rotor shaft part, and the excitation unit is located in the first rotor shaft part.
