Abstract (en)
[origin: WO2014206692A2] The invention relates to a method for operating an asynchronous machine (1) comprising a rotor (3) and a stator (2), in which a torque of the asynchronous machine (1) is adjusted by specifying a desired magnetic flux of a surrounding magnetic field of the stator (2) and specifying a desired slip between a rotational speed of the rotor (3) 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.
