Abstract
A rotating electric machine includes a stator having a winding head at each axial end and including a rotor, which is rotatably mounted in an opening in the stator and which has a rotor shaft and a laminated rotor core. The electric machine includes a bearing unit for the rotatable mounting of the rotor shaft with respect to the laminated rotor core, a transmission unit, a coupling unit, which is designed to provide at least two coupling states for coupling the rotation of the rotor shaft to the laminated rotor core and, in at least one of the coupling states, to couple the rotor shaft to the laminated rotor core by means of the transmission unit.

A rotating electric machine comprising:
- a stator having a winding head at each axial end,
- a rotor, which is rotatably mounted in an opening in the stator and which has a rotor shaft and a laminated rotor core,
- a bearing unit for rotatable mounting of the rotor shaft with respect to the laminated rotor core,
- a transmission unit,
- a coupling unit, which is designed to provide at least two coupling states for coupling rotation of the rotor shaft to the laminated rotor core and, in at least one of the coupling states, to couple the rotor shaft to the laminated rotor core by means of the transmission unit, the coupling unit including an actuator, which is arranged in the rotor shaft and is displaceable in an axial direction of the rotor shaft, for actuating the coupling unit, and
- a fluidic drive unit for driving the actuator.
