An electric motor for a hybrid drive of a vehicle comprises a rotor and a stator. The stator surrounds the rotor and the rotor is fastened to a rotor carrier. A rotor laminated core of the rotor is connected to the rotor carrier by a tongue-and-groove connection and a transverse interference fit. To form the transverse interference fit, the rotor laminated core may have, for bracing on the rotor carrier, a smaller radius than the rotor carrier.
