An electric drive unit for a hybrid drive, in particular for a vehicle, has an increased power output and degree of efficiency, while thermal loading as well as required installation space and manufacturing costs are minimized. The electric drive unit has an asynchronous machine with a rotor with a rotor cage, in particular a rotor cage which is formed with copper conductors. The asynchronous machine is formed with a stator having a shaft winding. The shaft winding is formed with a device for star-delta changeover. The rotor is formed with a rotor internal cooling device. A step-up gear mechanism is arranged in a power train between the rotor and the output element. There is also described a hybrid drive device with an electric drive unit, and a vehicle that has an electric drive unit and/or a hybrid drive device.

An electric motor includes a stator and a rotor rotatably mounted to the stator. The rotor includes a rotary shaft, a rotor main body attached around the rotary shaft, the rotor main body being rotatable under the interaction between the rotor main body and the stator when the winding is energized. The rotor main body and the rotary shaft are in a loose fitting with each other to allow a rotation speed difference being existed between the rotor main body and the rotary shaft during startup of the rotor. A time-delayed synchronization mechanism is connected between the rotary shaft and the rotor main body and configured to eliminate, with time delay, the rotation speed difference between the rotor main body and the rotary shaft.
