Abstract

The object of the invention is a synchronous machine, which is controllable by means of a frequency converter connected to it. The synchronous machine comprises a stator winding, which comprises between the synchronous machine's two terminals at least a first sub-coil (Upl,Vpl,Wpl) and a second sub-coil (Up2,Vp2,Wp2), onto which a voltage essentially of the same amplitude is induced when the synchronous machine is rotating. Furthermore, the synchronous machine comprises a switching device, by means of which the first sub-coil (Upl, Vpl, Wpl) and the second sub-coil (Up2,Vp2,Wp2) are connectible in series with each other when the switching device (K1;K2,K3) is in the rest position in such a way that their voltages are opposite and that the voltage in the terminals (L1,L2,L3) of the synchronous machine is essentially zero when the synchronous machine is disconnected from the frequency converter controlling it.
