    摘要: A switching device and method are disclosed for terminating a braking process of a three-phase AC motor. The braking process of the AC motor is performed by way of a first and second thyristor. During the braking process of the AC motor, in a first step the first thyristor is actuated in such a way that a braking current is fed to the AC motor, and therefore a torque which brakes the AC motor is produced. In a second step the second thyristor is actuated in such a way that, when the first thyristor is quenched, the braking current is taken on by the second thyristor and the braking torque is maintained. The two steps are repeated during the braking process; wherein the second step is suppressed during the braking process after a last actuation of the first thyristor.

    摘要: A method is disclosed for determining a phase failure in an electrical device for driving or monitoring a three-phase AC motor, wherein the electrical device comprises a first, a second and a third line. In order to detect a phase failure in a line in the three-phase electrical device, in particular in a soft starter, the phase failure in the third line is determined by analysing the first and second lines, wherein the analysis includes: determining a value which characterizes a phase shift between a current in the first and second lines, and outputting a signal if the value which has been determined is in a range of values which characterizes a phase failure in the third line.

    摘要: A method is disclosed for slowing-down control of an asynchronous machine, wherein the value of a start energy is determined and stored while the asynchronous machine is being run up from being stationary to the operating rotation speed. The asynchronous machine is braked, in the reversing mode, with braking energy which corresponds to the start energy multiplied by a correction factor wherein the correction factor assumes a value between 0 and 1. In at least one embodiment, the asynchronous machine is braked further by DC braking after braking has been carried out in the reversing mode.
