摘要： The problem of the invention is to achieve a connection or application of a converter to a rotating asynchronous machine, which is operated without an encoder, without a high current and without a torque surge. The mechanical system and the controlling system are not to be overloaded. The method is also to be capable of functioning independently of the residual magnetism. A method is proposed as a control unit, which employs an inverter or converter, in order to power the asynchronous machine (5), which rotates at a mechanical speed. The asynchronous machine is regulated by the control unit. A stator current vector (i s) is ascertained from measured currents of the stator windings of the asynchronous machine (5) and a rotating stator voltage vector (u s). A calculation of a stator flux change vector is performed from the stator current vector (i s), the stator voltage vector (u s), and a stator resistance (Rs) according to a motor model (100). An angle difference (?) between the stator current vector (i s) and the stator change vector is calculated. This angle difference (?) is regulated to a target value of 90° or -90°, wherein an output signal of said controller corresponds to a rotating field frequency (?) of the voltage vector of said stator which is to be applied. A regulation of an amplitude of the stator voltage vector is performed via a current controller (51), to which the difference of a current target value and a variable which corresponds to the amplitude of the stator current is provided at the input as the control difference (51a).
