Abstract

The invention relates to a method and a device for restarting an induction motor (16) which rotates as a consequence of a moment of inertia. According to the invention, an acceleration value (a) is calculated by means of derived remanence frequency values (fRa,fRe), with which frequency adjustment values (f'St) are interpolated which control the output frequency (fw) of the frequency converter (2), and a flux is built up in the machine (16) during interpolation of the frequency control values (f'St) by increasing a voltage adjustment value (uSt) of the output voltage (uR,S,T) of the frequency converter (2) in a controlled manner. A drive (2, 16) can thus be captured without shock or torque, the catchment speed being dependent only on the rotor time constant. <IMAGE>
