摘要：
In order to compensate for the effects of mechanical oscillations of the salient pole rotor in a synchronous machine in a simple manner, control coils are provided which generate a controllable quadrature-axis magnetic field. The control coils are arranged on the salient pole rotor in such a way that the quadrature-axis magnetic field generated by the control coils is superimposed in the air gap on the controllable direct-axis magnetic field generated by exciting coils enclosing each pole body of the salient pole rotor.
