| 发明名称 | Method and device for operating an asynchronous machine, and an asynchronous machine | ||
| 摘要 | 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. | ||

| 主权项 | 1. A method for operating an asynchronous machine comprising a rotor and a stator, the method comprising: adjusting a torque of the asynchronous machine by specifying a desired magnetic flux of a surrounding magnetic field of the stator and by specifying a desired slip between a rotational speed of the rotor and the rotational speed of the surrounding magnetic field, and changing, at least in a load condition and when a rotary frequency of the surrounding magnetic field of the stator is equal to zero, a selection from a group of the desired magnetic flux and the desired slip with constant torque in such a way that an actual rotary frequency of the surrounding magnetic field is not equal to zero. | ||
