The invention relates to a method for operating an asynchronous machine () comprising a rotor () and a stator (), in which a torque of the asynchronous machine () is adjusted by specifying a desired magnetic flux of a surrounding magnetic field of the stator () and specifying a desired slip between a rotational speed of the rotor () and the rotational speed of the surrounding magnetic field. According to the invention, at least in the load condition and when a rotary frequency of the surrounding magnetic field of the stator is equal to zero, the desired magnetic flux and/or the desired slip with constant torque is changed in such a way that an actual rotary frequency of the surrounding magnetic field is not equal to zero.

Method and device for operating an asynchronous machine, and an asynchronous machine

A method and a device for controlling the drive unit of a vehicle make possible an effective kinesthetic signaling of an event. Based on a detection of the event, an output variable of the drive unit is changed in a stepwise manner, as a function of whether the vehicle is in an overrun state or an acceleration state.
